Abstract

The Bates Large Acceptance Spectrometer Toroid (BLAST) experiment was operated at the MIT-Bates Linear Accelerator Center from 2003 until 2005. The experiment was designed to exploit the power of a polarized electron beam incident on polarized targets of hydrogen and deuterium to measure, in a systematic manner, the neutron, proton, and deuteron form factors as well as other aspects of the electromagnetic interaction on few-nucleon systems. We briefly describe the experiment, and present and discuss the numerous results obtained., United States. Dept. of Energy, National Science Foundation (U.S.)

Abstract

We report on the design and performance of compact detector packages currently installed in the four magnetic out-of-plane spectrometers for electron scattering experiments at the MIT-Bates Linear Accelerator Center. The detector packages have been designed to meet the mechanical requirements arising from out-of-plane particle detection. They offer good trajectory and momentum reconstruction, particle identification and time-of-flight measurements for electrons, pions, protons, and deuterons with large momentum bites and in broad kinematical ranges and high luminosities. The detectors have so far been used with great success in out-of-plane measurements of 12C(e→,e′p), 2H(e→,e′p), virtual Compton scattering below pion threshold and in studies of the N→Δ transition in both exclusive reaction channels 1H(e→,e′p)π0 and 1H(e→,e′π+)n. © 2002 Elsevier Science B.V.

Abstract

High-precision 1H(e, elp)φ0 measurements at Q2 = 0.126 (GeV/c)2 are presented. It allows the determination of quadrupole amplitudes in the γ*N → △ transition, in which the reliability of electroproduction models was simultaneously tested. The derived quadrupole-to-dipole (I = 3/2) amplitude ratios, RSM = (-6.5 ± 0.2stat+sys ± 2.5mod)% and REM = (-2.1 ± 0.2stat+sys ± 2.0mod)%, are dominated by model error.

Abstract

Measurements of the 2H(e→, e′p)n reaction were performed with the out-of-plane magnetic spectrometers (OOPS) at the MIT-Bates Linear Accelerator. The longitudinal-transverse, fLT and f′LT, and the transverse-transverse, fTT, interference responses at a missing momentum of 210MeV/c were simultaneously extracted in the dip region at Q2 = 0.15(GeV/c)2. In comparison to models of deuteron electrodisintegration, the data clearly reveal strong effects of relativity and final-state interactions and the importance of two-body meson-exchange currents and isobar configurations. We demonstrate that such effects can be disentangled by extracting these responses using the novel out-of-plane technique. © 2001 The American Physical Society.

Abstract

We report a precision measurement of the deuteron tensor analyzing powers T[subscript 20] and T[subscript 21] at the MIT-Bates Linear Accelerator Center. Data were collected simultaneously over a momentum transfer range Q=2.15–4.50 fm[superscript -1] with the Bates Large Acceptance Spectrometer Toroid using a highly polarized deuterium internal gas target. The data are in excellent agreement with calculations in a framework of effective field theory. The deuteron charge monopole and quadrupole form factors G[subscript C] and G[subscript Q] were separated with improved precision, and the location of the first node of G[subscript C] was confirmed at Q=4.19±0.05 fm[superscript -1]. The new data provide a strong constraint on theoretical models in a momentum transfer range covering the minimum of T[subscript 20] and the first node of G[subscript C]., National Science Foundation (U.S.), United States.

Abstract

Experimental details of a virtual Compton scattering (VCS) experiment performed on the proton at the MIT-Bates out-of-plane scattering facility are presented. The VCS response functions P[scubscript LL]−P[scubscript TT]/P[scubscript TT]ɛɛ and P[scubscript LT] have been measured at Q[superscript 2]=0.057 GeV[superscript 2]/c[superscript 2]. The generalized electric and magnetic polarizabilities, α(Q[superscript 2]) and β(Q[superscript 2]), and the mean-square electric polarizability radius(r[subscript α][superscript 2]) are obtained from a dispersion analysis of the data. The results are in good agreement with O(p[superscript 3]) heavy baryon chiral perturbation and indicate the dominance of mesonic effects in the polarizabilities., United States.

Abstract

Electrochemical cells containing two electrodes dipped in an ionic solution are widely used as charge accumulators, either with polarizable (supercapacitor) or nonpolarizable (battery) electrodes. Recent applications include desalination ("capacitive deionization") and energy extraction from salinity differences ("capacitive mixing"). In this Letter, we analyze a general relation between the variation of the electric potential as a function of the concentration and the salt adsorption. This relation comes from the evaluation of the electrical and mechanical energy exchange along a reversible cycle, which involves salt adsorption and release by the electrodes. The obtained relation thus describes a connection between capacitive deionization and capacitive mixing. We check this relation with experimental data already reported in the literature, and moreover by some classical physical models for electrodes, including polarizable and nonpolarizable electrodes. The generality of the relation makes it very useful in the study of the properties of the electric double layer. © 2012 American Physical Society.

Abstract

The ultra-thin gas targets used in storage ring internal target experiments allow low energy, heavy nuclei to emerge from the target region. A detector capable of analyzing these nuclei provides unique access to many nuclear reactions. We report here the first use of such a detector in conjunction with a polarized He-3 internal target and a polarized electron beam. The results of using the detector as a luminosity monitor and as a polarimeter to measure the product of beam and target polarizations are presented. The ability to study coherent pion production via the reactions 3 (H) over right arrow e((e) over right arrow,e'' He-3)pi(0) and 3 (H) over right arrow e((e) over right arrow,e'' H-3)pi(+) is shown along with the ability of the detector to unambiguously separate the two- and threebody breakup channels of the reaction 3 (H) over right arrow e((e) over right arrow,e'' p).

Abstract

We report on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into an electron storage ring at a beam energy of 720 MeV. A Siberian snake was employed to preserve longitudinal polarization at the interaction paint. Vector-polarized deuterium was produced by an atomic beam source and injected into an open-ended cylindrical cell, internal to the electron storage ring. The spin correlation parameter A(ed)(V) was measured for the reaction 2 (H) over right arrow((e) over right arrow, e'' n)p at a four-momentum transfer squared of 0.21 (GeV/c)(2) from which a value for the charge form factor of the neutron was extracted.

Abstract

Recent studies of neutrino oscillations have established the existence of finite neutrino masses and mixing between generations of neutrinos [1]. The combined results from studies of atmospheric neutrinos, solar neutrinos, reactor antineutrinos and neutrinos produced at accelerators paint an intriguing picture that clearly requires modification of the standard model of particle physics. These results also provide clear motivation for future neutrino oscillation experiments as well as searches for direct neutrino mass and nuclear double-beta decay. I will discuss the program of new neutrino oscillation experiments aimed at completing our knowledge of the neutrino mixing matrix.

Abstract

The development of a knowledge model applied to fixture design is a complex task. The main purpose of such model is the development of a knowledge-based application to assist fixture designers. It comprises a detailed specification of the types and structures of data involved in the execution of the inference process needed to create a fixture solution for machining a raw part. A development method together with a knowledge model for automating fixture design is proposed. The development was divided into three parts: Design Process Model, definition of Top-level functional functions and Product Knowledge Model. Adopting a functional design approach, the fixture design solution was created in two levels: functional and detailed. The functional level is based on fixture functional elements and the detailed one is based on fixture commercial elements. The definitions and concepts used in the application are specified in several Units of Knowledge (UoK) that comprises the Fixture Knowledge Model. Common Knowledge Analysis and Design Structuring (CommonKADS), Methodology and software tools Oriented to KBE Applications (MOKA), Integrated DEFinition for Function Modelling (IDEF0) and Unified Modelling Language (UML) are the methodologies and techniques used in the proposed method. Finally, a prototype KBE application for fixture design was developed.

Abstract

We present a measurement of the induced proton polarization P-n in pi(0) electroproduction on the proton around the Delta resonance. The measurement was made at a central invariant mass and a squared four-momentum transfer of W=1231 MeV and Q(2)=0.126 GeV2/c(2), respectively. We measured a large induced polarization, P-n = -0.397 +/- 0.055 +/- 0.009. The data suggest that the scalar background is larger than expected from a recent effective Hamiltonian model.

Abstract

We report an absolute measurement of the tensor analyzing powers T-20 and T-22 in elastic electron-deuteron scattering at a momentum transfer of 1.6 fm(-1). The novel approach of this measurement is the use of a tensor polarized H-2 target internal to an electron storage ring, with in situ measurement of the polarization of the target gas. Scattered electrons and recoil deuterons were detected in coincidence with two large acceptance nonmagnetic detectors. The techniques demonstrated have broad applicability to further measurements of spin-dependent electron scattering.

Abstract

A status report is given on experiment 91‐12, which is the first internal target experiment performed at the internal target facility of NIKHEF. The aim of this experiment is to measure the asymmetry in the (e,e′p) reaction from a tensor polarized deuterium target with unpolarized electrons. An update on the experimental setup and results of an extensive set of test measurements are presented.
