Abstract

MHD stability of NBI heated plasmas and impacts of MHD modes on plasma confinement are intensively studied in the Large Helical Device (LHD). Three characteristic MHD instabilities were observed, that is, (1) pressure driven modes excited in the plasma edge, (2) pressure driven mode in the plasma core, and (3) Alfvén eigenmodes (AEs) driven by energetic ions. MHD mode excited in the edge region accompanies multiple satellites, and is called Edge Harmonic Modes (EHMs). EHM sometimes has a bursting character. The bursting EHM transiently decreases the stored energy by about 15 percents. In the plasma core region, m=2/n=1 pressure driven mode is typically destabilized. The mode often induces internal collapse in the higher beta regime more than 1 percent. The internal collapse appreciably affects the global confinement. Energetic ion driven AEs are often detected in NBI-heated LHD plasmas. Particular AE with the frequency 8-10 times larger than TAE-frequency was detected in high beta plasmas more than 2 percent. The AE may be related to helicity-induced AE. Excitation of these three types of MHD instabilities and their impacts on plasma confinement are discussed.

Abstract

The Large Helical Device (LHD) is the world's largest heliotron-type device with I = 2, m = 10 continuous superconducting helical coils and three pairs of superconducting poloidal coils. The major and minor radii of the plasma are 3.6 to 3.9 and 0.6 to 0.65 m, respectively. A plasma with an elliptic cross section confined in the helical magnetic field rotates poloidally along the magnetic axis and has no axial symmetry. For the installation of various kinds of diagnostic instruments, large-sized ports are equipped. The diameter of the largest horizontal ports is 2410 mm, which enables us to easily access the full plasma cross section with multichannel viewing chords aligned parallel to one another. For the precise measurement of plasma quantities in a three-dimensional helical plasma, an extensive set of diagnostics has been developed with national and international collaborators and is routinely operated in LHD. The diagnostic system now consists of ∼50 measuring instruments and includes many challenging diagnostics that have been developed and operated for the study of LHD plasma confinement. These are classified as profile diagnostics, fluctuation diagnostics, and advanced diagnostics, some of which are selected for introduction in this article. In addition, diagnostics for the divertor and for energetic particles are discussed, along with topics that are somewhat unique to helical devices such as diagnosing three-dimensional phenomena and flux surface mapping. This large number of diagnostics in LHD rely on a data acquisition system that has broken world records for the amount of information accumulated in one shot. Finally, looking to the near future, countermeasures have been taken to protect diagnostics from the neutrons and gamma fluxes anticipated during deuterium-deuterium experiments, such as placing much of the diagnostic instrumentation behind a 2-m-thick concrete biological shield encompassing the LHD test cell.

Abstract

Reversed-shear Alfvén eigenmodes were observed for the first time in a helical plasma having negative q0'' (the curvature of the safety factor q at the zero shear layer). The frequency is swept downward and upward sequentially via the time variation in the maximum of q. The eigenmodes calculated by ideal MHD theory are consistent with the experimental data. The frequency sweeping is mainly determined by the effects of energetic ions and the bulk pressure gradient. Coupling of reversed-shear Alfvén eigenmodes with energetic ion driven geodesic acoustic modes generates a multitude of frequency-sweeping modes.

Abstract

We investigate complex materials by performing "Virtual Experiments" starting from three-dimensional images of grain packs obtained by X-ray CT imaging [1]. We apply this technique to granular materials by reconstructing a numerical samples of ideal spherical beads with desired (and tunable) properties. The resulting "virtual packing" has a structure that is almost identical to the experimental one. However, from such a digital duplicate we can calculate several static and dynamical properties (e.g. the force network, avalanche precursors, stress paths, stability, fragility, etc.) which are otherwise not directly accessible from experiments. Our simulation code handles three-dimensional spherical grains and it takes into account repulsive elastic normal forces, frictional tangential forces, viscous damping and gravity. The system can be both simulated within a vessel or with periodic boundary conditions.

231. Enhancement of para-selectivity in the phenol oxidation with H2O2 over Ti-MCM-68 zeolite catalyst.

Abstract

Although titanium silicalite-1 (TS-1) with an MFI framework (interconnected 10-ring micropores) is a useful catalyst for phenol oxidation, Ti-MCM-68, a novel MSE-type titanosilicate with 12-ring and 10-ring micropores, has been developed as a phenol oxidation catalyst with high activity and selectivity toward the p-isomer, hydroquinone. This report describes the improvement in catalytic activity and para-selectivity of Ti-MCM-68 for phenol oxidation. Thermal treatment after Ti insertion significantly enhanced the catalytic activity of Ti-MCM-68, mainly due to an improvement in the hydrophobicity in the micropores. Silylation of the external surface of Ti-MCM-68 with Ph2SiCl2, followed by Ti insertion and calcination, showed greater para-selectivity, indicating that the selective formation of p-isomers occurred within one-dimensional 12-ring micropores in the Ti-MCM-68. The addition of ethanol as a cosolvent to the reaction mixture resulted in the best para-selectivity (＞94%) and activity among the modified Ti-MCM-68 catalysts. [ABSTRACT FROM AUTHOR]

Abstract

To improve the detectability of gastrointestinal (GI) bleeding, we have developed a new method, 'sequential subtraction scintigraphy' (SSS) with 99Tcm-labelled red blood cells (RBC). Sequential subtraction scintigrams were obtained by subtracting 5 min interval images from each other using a digital gamma camera. With this method, we are able to detect the bleeding site and calculate the bleeding rate earlier because of the lower background activity. The results of the present study demonstrate that the minimum detectable bleeding rate was 0.05 ml min-1 in both a phantom and an animal model. The minimum detectable activity volumes within 10 min were 0.5 ml by SSS and more that 3 ml by conventional non-subtraction scintigraphy (CNS). The bleeding rates calculated with the subtraction method correlated well with the actual syringe pump rates. The detectability of GI bleeding by SSS and CNS in animal models was compared using the area under receiver operator characteristic (ROC) curves. The results showed that SSS significantly increased the area under the ROC curves from 0.55 +/- 0.05 to 0.79 +/- 0.04 for the 10 min image set and from 0.65 +/- 0.05 to 0.83 +/- 0.04 for the 30 min image set (Z = 5.45, P < 0.0001 and Z = 4.36, P < 0.0001, respectively). These results suggest that sequential subtraction scintigraphy with 99Tcm-RBC is an effective method for the early detection of GI bleeding when compared with the conventional non-subtraction method.

Abstract

New stellarator experiments have been launched since the last compilation of the international stellarator database in 1995. Parameter regimes have been extended by Large Helical Device (LHD), and a variety of improved modes have been found since then. The revision of the international stellarator database has been initiated, driven by these emerging interests and by the requirements for a reactor assessment. Some provisional issues are discussed. An understanding of configurational ef fects is a prerequisite to the derivation of a unified scaling. Differences in magnetic geometry are influential in characterizing energy confinement. The results from the magnetic axis and elongation scans in LHD are high-lighted. Comparison with tokamak confinement is also addressed. The revision of the database is in progress, and this paper is an interim report.
