A SiC avalanche-diode with P-N structure has been developed to utilize it as a surge voltage absorber in power converter circuit. To evaluate the static characteristics, correlation between clamping voltage and avalanche current has been measured. The temperature dependence of the clamping voltage was also measured. The effectiveness in suppressing surge voltage by SiC avalanche-diode has been demonstrated in step-down DC/DC converter. By comparative studies with the RC and RCD snubbers, sufficient performance has been accomplished with avalanche-diode. Moreover, by measuring power efficiency, it is confirmed that the avalanche-diode effectively suppress the surge voltage without introducing additional power dissipation.

The effects induced by parasitic inductance were studied in a neutral point clamped (NPC) inverter. The energy stored in the parasitic inductance by the output current causes a surge voltage during the turn-off period of semiconductor switches. The effect is serious in a magnet power supply for which a large excitation current is required. It is predicted by a circuit analysis that the parasitic inductance causes an electrical breakdown of the semiconductor switches. It was found that the most promising way to mitigate the effect is to reduce the parasitic inductance. With newly developed circuitry and layout of an NPC inverter, cancelation of the induced magnetic field, which is based on Ampere׳s circuital law, in power devices has been accomplished. The newly developed NPC inverter has been operated successfully with both a resistive dummy load and the dipole magnets in the main ring synchrotron at the J-PARC facility.

The mechanism that generates common-mode noise in inverter circuits, which are widely used in magnet power supplies, was evaluated by a circuit simulation. By following asymmetric operational sequences, pulsed voltage is applied to the parasitic capacitance of power cables that causes a common-mode current at each switching period of the semiconductor switches. Common-mode noise was also found to disturb the normal-mode excitation current by inducing higher frequency components in the applied voltage to the magnet. To eliminate the disturbing effect by the common-mode noise, a newly developed operational method that uses a neutral point clamped, NPC, inverter with reduced switching sequences was evaluated both by a circuit simulation and experimentally. The operational method for the NPC inverter could sufficiently reduce the common-mode noise. A high-power test operation performed using 16 bending magnets at the J-PARC facility achieved a ripple of less than 1 ppm in the excitation current.

A fast extraction kicker magnet for the main ring of J-PARC has been developed. A lumped constant type magnet is employed for its structural simplicity and stability in high-voltage operation. A disadvantage of the lumped constant type, a slow rise time, was alleviated by the adoption of a newly developed magnetic pulse compression system. The effectiveness of the magnetic pulse compression system in sharpening the excitation current was confirmed both by a circuit simulation and experimentally. The newly developed fast extraction kicker system was operated successfully with a 30 kV charging voltage of the pulsed power supply. The required rise time of less than 1.1 μs was achieved in the measurement.

The 320 kA pulsed magnetic horn power supply with a novel magnetic energy recovery system for the T2K experiment has been developed. The magnetic energy once stored in the horn system during an excitation period by a pulsed current of 320 kA is recovered by a full-bridge circuit to the energy storage capacitors. Four switching arms by high-power thyristors in the full-bridge circuit are actively controlled for an efficient energy recovery process. Operational principle of the energy recovery system was proved by both the simulation study and the high-voltage test operation. Successful operations of the newly developed pulsed magnetic horn power supply were also confirmed by high-voltage test operations.

An effect induced by parasitic inductance in a pulsed power supply for a fast extraction kicker was studied. The parasitic inductance in high voltage capacitors for a low impedance pulse forming network disturbs a sharp rise of an excitation current. A high voltage capacitor with a coaxial structure to minimize the parasitic inductance is proposed. The effectiveness was confirmed experimentally. An impedance mismatch by a leakage inductance of a pulse transformer in a transmission line was studied. The effect is serious at the flat-top period of the excitation current. By introducing a compensation circuit, which is composed by a capacitor and a resistor, impedance matching was established. The pulsed power supply for the fast extraction kicker was operated at a charging voltage of 30 kV. A required rise time of less than 1.1 μs was achieved. The flatness was also confirmed to be in an acceptable value of less than 1%.

We report a measurement of the $\nu_\mu$ inclusive charged current cross sections on iron and hydrocarbon in the T2K on-axis neutrino beam. The measured inclusive charged current cross sections on iron and hydrocarbon averaged over the T2K on-axis flux with a mean neutrino energy of 1.51 GeV are $(1.444\pm0.002(stat.)_{-0.157}^{+0.189}(syst.))\times 10^{-38}\mathrm{cm}^2/\mathrm{nucleon}$, and $(1.379\pm0.009(stat.)_{-0.147}^{+0.178}(syst.))\times 10^{-38}\mathrm{cm}^2/\mathrm{nucleon}$, respectively, and their cross section ratio is $1.047\pm0.007(stat.)\pm0.035(syst.)$. These results agree well with the predictions of the neutrino interaction model, and thus we checked the correct treatment of the nuclear effect for iron and hydrocarbon targets in the model within the measurement precisions., Comment: 15 pages, 17 figures

The T2K experiment has observed electron neutrino appearance in a muon neutrino beam produced 295 km from the Super-Kamiokande detector with a peak energy of 0.6 GeV. A total of 28 electron neutrino events were detected with an energy distribution consistent with an appearance signal, corresponding to a significance of 7.3$\sigma$ when compared to 4.92 $\pm$ 0.55 expected background events. In the PMNS mixing model, the electron neutrino appearance signal depends on several parameters including three mixing angles $\theta_{12}$, $\theta_{23}$, $\theta_{13}$, a mass difference $\Delta m^2_{32}$ and a CP violating phase $\delta_{\mathrm{CP}}$. In this neutrino oscillation scenario, assuming $|\Delta m^2_{32}| = 2.4 \times 10^{-3}$ $\rm eV^2$, $\sin^2 \theta_{23} = 0.5$, and $\Delta m^2_{32} >0$ ($\Delta m^2_{32}, Comment: 8 pages, 6 figures

We report the first measurement of the neutrino-oxygen neutral-current quasielastic (NCQE) cross section. It is obtained by observing nuclear deexcitation $\gamma$-rays which follow neutrino-oxygen interactions at the Super-Kamiokande water Cherenkov detector. We use T2K data corresponding to $3.01 \times 10^{20}$ protons on target. By selecting only events during the T2K beam window and with well-reconstructed vertices in the fiducial volume, the large background rate from natural radioactivity is dramatically reduced. We observe 43 events in the $4-30$ MeV reconstructed energy window, compared with an expectation of 51.0, which includes an estimated 16.2 background events. The background is primarily nonquasielastic neutral-current interactions and has only 1.2 events from natural radioactivity. The flux-averaged NCQE cross section we measure is $1.55 \times 10^{-38}$ cm$^2$ with a 68\% confidence interval of $(1.22, 2.20) \times 10^{-38}$ cm$^2$ at a median neutrino energy of 630 MeV, compared with the theoretical prediction of $2.01 \times 10^{-38}$ cm$^2$., Comment: 10 pages, 6 figures

New data from the T2K neutrino oscillation experiment produce the most precise measurement of the neutrino mixing parameter theta_{23}. Using an off-axis neutrino beam with a peak energy of 0.6 GeV and a data set corresponding to 6.57 x 10^{20} protons on target, T2K has fit the energy-dependent nu_mu oscillation probability to determine oscillation parameters. Marginalizing over the values of other oscillation parameters yields sin^2 (theta_{23}) = 0.514 +0.055/-0.056 (0.511 +- 0.055), assuming normal (inverted) mass hierarchy. The best-fit mass-squared splitting for normal hierarchy is Delta m^2_{32} = (2.51 +- 0.10) x 10^{-3} eV^2/c^4 (inverted hierarchy: Delta m^2_{13} = (2.48 +- 0.10) x 10^{-3} eV^2/c^4). Adding a model of multinucleon interactions that affect neutrino energy reconstruction is found to produce only small biases in neutrino oscillation parameter extraction at current levels of statistical uncertainty., Comment: 8 pages, 4 figures. Final version as published in PRL, with very minor changes from initial version in response to referee comments

The T2K Collaboration reports evidence for electron neutrino appearance at the atmospheric mass splitting, vertical bar Delta m(32)(2)vertical bar approximate to 2.4 X 10(-3) eV(2). An excess of electron neutrino interactions over background is observed from a muon neutrino beam with a peak energy of 0.6 GeV at the Super-Kamiokande (SK) detector 295 km from the beam's origin. Signal and background predictions are constrained by data from near detectors located 280 m from the neutrino production target. We observe 11 electron neutrino candidate events at the SK detector when a background of 3.3 +/- 0.4(syst) events is expected. The background-only hypothesis is rejected with a p value of 0.0009 (3.1 sigma), and a fit assuming nu(mu) -> nu(e) oscillations with sin (2)2 theta(23) = 1, delta(CP) = 0 and vertical bar Delta m(32)(2)vertical bar = 2.4 X 10(-3) eV(2) yields sin (2)2 theta(13) = 0.088(-0.039)(+0.049)(stat + syst)., We thank the J-PARC accelerator team for the superb accelerator performance and CERN NA61 colleagues for providing essential particle production data and for their fruitful collaboration. We acknowledge the support of MEXT, Japan; NSERC, NRC and CFI, Canada; CEA and CNRS/IN2P3, France; DFG, Germany; INFN, Italy; Ministry of Science and Higher Education, Poland; RAS, RFBR and the Ministry of Education and Science of the Russian Federation; MEST and NRF, South Korea; MICINN and CPAN, Spain; SNSF and SER, Switzerland; STFC, U.K.; NSF and DOE, USA We also thank CERN for their donation of the UA1/NOMAD magnet and DESY for the HERA-B magnet mover system. In addition, participation of individual researchers and institutions in T2K has been further supported by funds from ERC (FP7), EU; JSPS, Japan; Royal Society, UK; DOE Early Career program, and the A. P. Sloan Foundation, USA Computations were performed on the supercomputers at the SciNet [115] HPC Consortium.

T2K has performed the first measurement of nu(mu) inclusive charged current interactions on carbon at neutrino energies of similar to 1 GeV where the measurement is reported as a flux-averaged double differential cross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and external data, including the results from the NA61/SHINE experiment. The data used for this measurement were taken in 2010 and 2011, with a total of 10.8 x 10(19) protons-on-target. The analysis is performed on 4485 inclusive charged current interaction candidates selected in the most upstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section is (phi) = (6.91 +/- 0.13(stat) +/- 0.84(syst)) x 10(-39) cm(2)/nucleon for a mean neutrino energy of 0.85 GeV., We thank the J-PARC accelerator team for the superb accelerator performance and CERN NA61 colleagues for providing essential particle production data and for their fruitful collaboration. We acknowledge the support of MEXT, Japan; NSERC, NRC and CFI, Canada; CEA and CNRS/IN2P3, France; DFG, Germany; INFN, Italy; Ministry of Science and Higher Education, Poland; RAS, RFBR and the Ministry of Education and Science of the Russian Federation; MEST and NRF, South Korea; MICINN and CPAN, Spain; SNSF and SER, Switzerland; STFC, UK; NSF and DOE, USA. We also thank CERN for their donation of the UA1/NOMAD magnet and DESY for the HERA-B magnet mover system. In addition, participation of individual researchers and institutions in T2K has been further supported by funds from: ERC (FP7), EU; JSPS, Japan; Royal Society, UK; DOE Early Career program, and the A.

The Tokai-to-Kamioka (T2K) experiment studies neutrino oscillations using an off-axismuon neutrino beam with a peak energy of about 0.6 GeV that originates at the Japan Proton Accelerator Research Complex accelerator facility. Interactions of the neutrinos are observed at near detectors placed at 280 m from the production target and at the far detector-Super-Kamiokande-located 295 km away. The flux prediction is an essential part of the successful prediction of neutrino interaction rates at the T2K detectors and is an important input to T2K neutrino oscillation and cross section measurements. A FLUKA and GEANT3-based simulation models the physical processes involved in the neutrino production, from the interaction of primary beam protons in the T2K target, to the decay of hadrons and muons that produce neutrinos. The simulation uses proton beam monitor measurements as inputs. The modeling of hadronic interactions is reweighted using thin target hadron production data, including recent charged pion and kaon measurements from the NA61/SHINE experiment. For the first T2K analyses the uncertainties on the flux prediction are evaluated to be below 15% near the flux peak. The uncertainty on the ratio of the flux predictions at the far and near detectors is less than 2% near the flux peak., We thank the J-PARC accelerator team for the superb accelerator performance and the J-PARC center for the continuous support of the T2K experiment. We are grateful to the NA61/SHINE collaboration and FLUKA team for their assistance to make our data-driven flux prediction.

A magnetic horn system to be operated at a pulsed current of 320 kA and to survive high-power proton beam operation at 750 kW was developed for the T2K experiment. The first set of T2K magnetic horns was operated for over 12 million pulses during the four years of operation from 2010 to 2013, under a maximum beam power of 230 kW, and $6.63\times10^{20}$ protons were exposed to the production target. No significant damage was observed throughout this period. This successful operation of the T2K magnetic horns led to the discovery of the $\nu_{\mu}\rightarrow\nu_e$ oscillation phenomenon in 2013 by the T2K experiment. In this paper, details of the design, construction, and operation experience of the T2K magnetic horns are described., Comment: 22 pages, 40 figures, also submitted to Nuclear Instrument and Methods in Physics Research, A

A resonant structure, induced by parasitic capacitance and inductance, was studied in a solid state pulsed power modulator for an induction synchrotron. Parasitic capacitors form a resonant structure in a switching arm with a self-inductance of the modulator circuit. The resonance induces a ringing in an acceleration voltage, causing an extra force to particles in the longitudinal direction. This effect is serious around the transition energy, because a mismatch exists between the particle distribution before the transition and a bucket shape after the transition. It was found that the most promising way to avoid this situation is to reduce the self-inductance of the modulator circuit. By sufficient reduction, an output waveform without any serious deterioration of flatness has been achieved by a newly developed power modulator.

The Tokai to Kamioka (T2K) experiment studies neutrino oscillations using a beam of muon neutrinos produced by an accelerator. The neutrinos travel from J-PARC on the east coast of Japan and are detected 295 kilometers further away in the Super-Kamiokande detector. A complex of near detectors located 280 meters away from the neutrino production target is used to better characterize the neutrino beam and reduce systematic uncertainties. The experiment aims at measuring electronic neutrino appearance ( ν μ → ν e oscillation) to measure the neutrino mixing angle θ 13 , and muon neutrino disappearance to measure the neutrino mixing angle θ 23 and mass splitting | Δ m 32 2 |. We report here electron neutrino appearance results using three years of data, recorded until the 2012 summer, as well as muon neutrino disappearance results based on the data coming from the first two years of the experiment.

Precise measurement of neutrino beam direction and intensity was achieved based on a new concept with modularized neutrino detectors. INGRID (Interactive Neutrino GRID) is an on-axis near detector for the T2K long baseline neutrino oscillation experiment. INGRID consists of 16 identical modules arranged in horizontal and vertical arrays around the beam center. The module has a sandwich structure of iron target plates and scintillator trackers. INGRID directly monitors the muon neutrino beam profile center and intensity using the number of observed neutrino events in each module. The neutrino beam direction is measured with accuracy better than 0.4 mrad from the measured profile center. The normalized event rate is measured with 4% precision., Comment: 32 pages, 27 figures, submitted to Nucl. Instr. and Meth. A

The T2K experiment observes indications of $\nu_\mu\rightarrow \nu_e$ appearance in data accumulated with $1.43\times10^{20}$ protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with $|\Delta m_{23}^2|=2.4\times10^{-3}$ eV$^2$, $\sin^2 2\theta_{23}=1$ and $\sin^2 2\theta_{13}=0$, the expected number of such events is 1.5$\pm$0.3(syst.). Under this hypothesis, the probability to observe six or more candidate events is 7$\times10^{-3}$, equivalent to 2.5$\sigma$ significance. At 90% C.L., the data are consistent with 0.03(0.04)$, Comment: 20 pages, 6 figures, version published in PRL

The Ring-Imaging Cherenkov (RICH) and the Time-of-Flight (ToF) systems provide identification of charged particles for the PHENIX central arm. The RICH is located between the inner and outer tracking units and is one of the primary devices for identifying electrons among the very large number of charged pions. The ToF is used to identify hadrons and is located between the most outer pad chamber (PC3) and the electromagnetic calorimeter. A Time Zero (T0) counter that enhances charged particle measurements in p–p collisions is described. Details of the construction and performance of both the RICH, ToF and T0 are given along with typical results from the first PHENIX data taking run.

This article describes the utilization and satisfaction patterns of Native Hawaiian elders with the Ke Ola Pono No Na Kupuna ("Good Health and Living for the Elderly") project funded under Title VI-B of the Older Americans Act. Data were collected through a self-administered questionnaire. Its unique, one of a kind, culturally specific program, which includes traditional Native Hawaiian meals, has a number of implications for policy considerations in designing aging programs that can serve ethnic minority aged more effectively. Changes in current federal policy that would enable federally mandated aspects of programs to provide for greater flexibility in providing culturally relevant programs and services for ethnic minorities would help to surmount some of the current problems and barriers to service delivery and utilization by ethnic minority groups. Allowing for greater involvement of ethnic minorities in program design will help to assure culturally relevant and appropriate activities and services and may increase the likelihood of success due to a sense of personal ownership and self-responsibility on the part of those involved.

This article describes the sociodemographic characteristics, self-ratings of health status, life satisfaction and health practices of Pacific Asian and Native Hawaiian elderly groups. The data were gathered from two separate, non-equivalent elderly cohorts enrolled in an elderly self-care education program in Hawaii during the period 1989-1992.The findings generally reflected favorable self-ratings of health status, high life satisfaction levels, and positive health practices for both of these minority elderly groups. The exceptions regarding several health practices relate to snacking between meals, overweight problems and insufficient sleep for a sizable proportion of both groups. Slight to moderate differences between the two groups were also evident in 1) eating habits; 2) snacking; 3) types of physical activities; 4) weight control; 5) sleep patterns; 6) alcohol use; and 7) smoking.Despite the article's exploratory nature and limitation in the generalizability of its findings, the data of fer a beginning database for Asian and Pacific Island elderly which is sorely lacking.

We report a measurement of muon-neutrino disappearance in the T2K experiment. The 295-km muon-neutrino beam from Tokai to Kamioka is the first implementation of the off-axis technique in a long-baseline neutrino oscillation experiment. With data corresponding to 1.43 × 10(20) protons on target, we observe 31 fully-contained single μ-like ring events in Super-Kamiokande, compared with an expectation of 104 ± 14(syst) events without neutrino oscillations. The best-fit point for two-flavor νμ → ντ oscillations is sin 2(2θ(23)) = 0.98 and |Δm(2)(32)| = 2.65 × 10(−3) eV2. The boundary of the 90% confidence region includes the points (sin2 (2θ(23)), |Δm(2)(32)|) = (1.0, 3.1 × 10(−3) eV2), (0.84, 2.65 × 10(−3) eV2) and (1.0, 2.2 × 10(−3) eV2)., Physical Review D, 85 (3), ISSN:1550-7998, ISSN:0556-2821, ISSN:1550-2368

The slow cycling main ring synchrotron (MR) is located the furthest downstream in the J-PARC accelerator cascade. It became available for user operation in 2009 and provides high-intensity 30 GeV proton beams for various experiments on particle and nuclear physics. The MR has two beam extraction systems: a fast extraction system for beam delivery to the neutrino beam line of the Tokai-to-Kamioka (T2K) experiment and a slow extraction system for beam delivery to the hadron experimental hall. After a nine-month beam shutdown during the recovery from the Great East Japan Earthquake, the J-PARC facility resumed beam operation in December 2011. The MR delivers a 160–200kW beam to the T2K experiment and a 3.5–6kW beam to users in the hadron experimental hall. In this paper, a brief review of the MR and the recent status of beam operation are presented. Near-future plans for a beam intensity upgrade are also discussed.

(BaSrCa)TiO3 ceramics used as varistors are investigated by high-resolution electron microscopy with the aid of image simulation. Two samples prepared by slightly different reducing heat treatments are observed. One is composed of large crystalline grains and microcrystalline regions (or grains), both of which have the same chemical composition, and also amorphous grain boundary areas rich in SiO2, MgO, and BaO. The other is only composed of well-developed crystalline grains with a boundary of facet structure. The interface between facets of the bicrystals is the composition plane of the (111) twin, and is not a Ti layer but a (BaSrCa)–O3 layer. The atomic projection of the crystals near the grain boundary is also described. Les ceramiques de (BaSrCa)TiO3 produits a l'usage des varistors sont recherches par le microscope electronique haut-resoluble des transmissions, avec des images simulees par ordinateur. Deux specimens prepares par peu differents traitements thermiques sont observes. L'un se compose des grands grains cristallins, les regions (ou les grains) microcristallines de la měme composition chimique et les bornes amorphes, riches en SiO2, MgO et BaO au milieu des grains. L'autre se compose des grains d'un cristal bien developpe avec la borne a facettes. La frontiere entre les deux cristaux en les facettes est un plan composant de la macle de (111), et n'est pas du couche de Ti mais une couche de (BaSrCa)–O3. La projection des atomes en les cristaux pres de la frontiere est decrit aussi bien.

The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle {\theta}_{13} by observing {\nu}_e appearance in a {\nu}_{\mu} beam. It also aims to make a precision measurement of the known oscillation parameters, {\Delta}m^{2}_{23} and sin^{2} 2{\theta}_{23}, via {\nu}_{\mu} disappearance studies. Other goals of the experiment include various neutrino cross section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem., Comment: 33 pages, 32 figures, Submitted and accepted by NIM A.

A novel class of membraneous electrolyte has been prepared by incorporating a complex of liquid polyethers and LiClO 4 in a microporous membrane. Surface tension and contact angle measurements suggested that numbers of polymer electrolyte solutions can be immobilized in pores of a microporous membrane by taking advantage of capillary condensation force. Polyethers such as PEO, PPO, and PEO/PPO copolymers having an average MW from 240 to 340 were complexed with LiClO 4 and immobilized in pores of a polyethylene membrane with a thickness of 4 to 10 μm and a pore radius of about 0.01 μm. Ionic conductivity of the immobilized liquid membrane electrolytes reached to the order of 10 −4 S cm −1 and the effective resistance approached to 1 Ω cm 2 at room temperature. The conductivity data suggested that the immobilized liquid membrane electrolytes behaved as liquids in the ion transport.

A new particle acceleration method using pulsed induction cells was introduced in the super-bunch project at KEK. Unlike conventional RF acceleration, this acceleration method separates functions of acceleration and confinement. As a result, this acceleration method is capable of accelerating a very long bunch of beam or a wide mass range of particles. However, it is necessary to give a very fast pulsed- excitation to the magnetic material to induce an electric field to accelerate particles. Switching power supplies of high voltage output with very fast pulse-operation is one of the most important key technologies for this new acceleration method. Features of switching power supply developed for induction synchrotron is reported. The 31 kW MOSFET switch performed 1 MHz continuous operation with 15 nsec rise time.

A high density magnetic recording for a helical-scan tape recorder has been developed. Tape-head characteristics and a PRML-class 1 detecting method with adaptive digital equalization are discussed and a new auto tracking following technology has been proposed. Using these technologies, we have achieved symbol error rate less than 1*10E-5 at an area density of 268 Mbit/inch/sup 2/. As a result, we have successfully demonstrated an advanced tape streamer with a transfer rate of 24 Mbps and a capacity per cassette of 25 GB.

A proof of principle experiment of an Induction Synchrotron is scheduled in 2003 at the KEK 12GeV-PS. Proton bunches are accelerated with a 10kV of rectangular shaped induction voltage. An accelerating system consists of four induction cavities capable of individually generating a 2.5kV of output voltage. Each cavity is driven by a solid-state power modulator, which is operated at a revolution frequency of 600-800 kHz. The modulator circuit consists of MOS-FETs as switching element. Uniformity in the voltage waveform is crucial for the stable acceleration. Ringing in the voltage waveform caused by coupling of self-inductance of circuit and output capacitance of MOS-FETs deteriorates the uniformity. With the help of circuit analysis and simulation method of minimizing the self-inductance has been developed. Ratio of numbers of MOS-FETs in series and in parallel which defines the total output capacitance is also important to design the power modulator circuit. Power loss in MOS-FET is also important for stable operation of the power modulator. By the circuit analysis, it is also found that the output capacitance contributes to the power loss.

The performance of electrolyte plate matrices for molten carbonate fuel cells made by a fabrication method called the paper-making method is investigated. The matrix porosity obtained was within the preferable porosity range of about 60 to 70%. In the porosity range from 65 to 76% crossover leakage was kept to a minimum and was little affected by the thermal cycle. At porosities of less than 60%, crossover leakage increased. These results agreed with those obtained in a free thermal-cycle test in which an electrolyte plate was placed in a furnace and repeatedly heated and cooled. A single 200 cm/sup 2/ cell with an electrolyte plate of about 68% porosity produced by the paper-making method has been subjected to more than 8200 h of continuous operation. The degradation rate of the cell voltage was about 30 mu V/h. The main causes of this degradation were creepage of the electrolyte from the electrolyte plate and the reaction of the electrolyte with the reinforcing materials, such as alumina fiber. >

The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

However, long-term continuous measurement has not been achieved because the microdialysis probe recovery rate and the sensitivity of the glucose sensor decrease. To solve this problem, a new method for long-term continuous measurement of subcutaneous tissue glucose concentration using a microdialysis technique was developed. We assumed a model of standard glucose solutions of two different concentrations, which are perfused via a microdialysis probe inserted subcutaneously. The standard solutions are switched by changing the valve. One solution is higher in concentration than the tissue and the other is lower. By controlling the perfusion time ratio of the standard solutions, we will automatically be able to calculate the glucose concentration of the tissue from the ratio of perfusion time when the glucose sensor signal at the microdialysis probe outlet is steady. In our results, measurement error was less than 10% in the experiment using a larger-scaled hollow fiber instead of a microdialysis probe. This study suggests a method for continuous measuring of subcutaneous tissue glucose concentration without calibration.

Feasibility studies on capacitive energy storage and recovery in the main-ring synchrotron of the Japan Proton Accelerator Research Complex were conducted by circuit simulation. The estimated load fluctuation was 96 MVA in total for dipole magnets, which is likely to induce a serious disturbance in the main grid. It was found that the energy stored in the magnets after the excitation period can be recovered to the storage capacitor by controlling the voltage across the energy-storage capacitor using a pulse-width-modulation converter and reused in the next operational cycle. It was also found that the power fluctuation in the main grid can be reduced to 12 MVA. An experimental evaluation of an aluminum metalized film capacitor revealed that capacitance loss was induced by a fluctuating voltage applied to the storage capacitor when applying the proposed method. The capacitance loss was induced by corona discharge around the edges of segmented electrodes of a self-healing capacitor. The use of aluminum-zinc alloy was evaluated as a countermeasure to mitigate the effect induced by the corona discharge. For a zinc content of 8%, which was optimized experimentally, a capacitor with a sufficient life time expectancy of 20 years and a working potential gradient of 250 V/μm was developed.

A beam-switching magnet and the pulsed power supply it requires have been developed for the Japan Proton Accelerator Research Complex. To switch bunched proton beams, the dipole magnetic field must reach its maximum value within 40 ms. In addition, the field flatness should be less than 5 × 10(-4) to guide each bunched beam to the designed orbit. From a magnetic field measurement by using a long search coil, it was found that an eddy current in the thick endplates and laminated core disturbs the rise of the magnetic field. The eddy current also deteriorates the field flatness over the required flat-top period. The measured field flatness was 5 × 10(-3). By using a double-exponential equation to approximate the measured magnetic field, a compensation pattern for the eddy current was calculated. The integrated magnetic field was measured while using the newly developed open-loop compensation system. A field flatness of less than 5 × 10(-4), which is an acceptable value, was achieved.

We ranked prognostic factors to retrospectively evaluate the clinical significance of interferon alpha (IFN-alpha) therapy in patients with Robson stage IVB renal cell carcinoma. A total of 44 Robson stage IVB renal cancer patients were divided into 2 groups, one with more than 6 months administration of IFN-alpha (3-7 times a week: group A) and another without any IFN-alpha administration. The distribution of these 2 groups was not randomized. In addition to IFN-alpha therapy, survival was analyzed with respect to performance status (PS), mass reductive nephrectomy, concomitant use of other cytotoxic therapies, the number of metastatic organs, growth type, site of metastasis and the period of diagnosis, using a multivariate method with Cox proportional hazards regression. The multivariate analysis showed administration of IFN-alpha to be the most significant factor influencing a good prognosis. Improved survival was also significantly correlated with slow growing type and good PS. Among group A, a significant favorable prognosis was obtained in patients with the responses of no change (NC), partial response (PR) and complete remission (CR) 6 months after initiating administration of IFN-alpha, as well as with good PS and a slow growing type carcinoma. We conclude that IFN-alpha therapy might improve the prognosis of patients with Robson stage IVB renal cell carcinoma, especially, in cases when a greater than NC response is obtained after 6 months administration of IFN-alpha.

The trauma-injury severity-score (TRISS) methodology was developed in the United States to calculate the probability of survival for trauma patients presenting for emergency care.We assessed the utility of using the TRISS methodology to identify preventable trauma deaths and compared the results to peer review using explicit standards.Explicit peer review standards were developed by a focus group. The validity of these standards was evaluated by comparing the results of peer review performed by two independent expert panels. All trauma cases admitted to 10 centers in Japan between April 1, 1994, and March 31, 1996, were evaluated using the TRISS methodology. Cases with an expected probability of survival of more than 0.5 were considered preventable. These cases were subjected to peer review. Patients who were dead on arrival were excluded from analysis.Of 3,125 patients who were not dead on arrival, the TRISS methodology identified 2,525 as having a probability of survival greater than 0.5. In this group, 189 patients died; thus, 25.3% of all deaths were considered preventable by the TRISS method. Peer review found that only 11.2% of the deaths were preventable; thus, only 46.6% of preventable deaths identified by TRISS were confirmed by peer review. Agreement between the two expert peer review panels was very good (kappa = 0.62).TRISS can be used as a screening tool to identify potentially preventable trauma deaths. Peer review is appropriate to confirm preventability and to identify potential medical errors.

PURPOSE: To study the relationship between the MR findings and the clinical features in temporal lobe epilepsy in childhood (less than 10 years of age). METHODS: MR studies were performed with a 1.5-T imager on 38 temporal lobe epilepsy patients receiving drug therapy at the psychiatric department. These patients were divided into two groups according to their age at onset (10 years or less, 11 years or more). The two groups were compared in terms of the MR findings and clinical features. RESULTS: The 11 younger-onset patients included 5 with a high-signal area attributed to mesial temporal sclerosis. Clinically, all of these 5 patients had a history of "complex" febrile convulsions, which sharply distinguished them from the older-onset group. CONCLUSION: The analysis suggests that complex febrile convulsions in infancy can be associated with high-signal areas on MR attributed to mesial temporal sclerosis.
