Title: Final Technical Report on DOE Junior Faculty Development Award

Abstract

Over the course of this project we developed and contstructed the Colorado FRC facility, which included a custom vacuum vessel, high voltage and firing circuitry, two plasma gun electrodes, and pumping system, and several diagnostics. Density measurements were made with a multichannel CO{sub 2} (10.6 μm) laser interferometer. We also developed and a high-resolution magnetic probe array for 3-axis measurements of magnetic fluctuations. We constructed and implemented a triple Langmuir probe for making time-resolved measurements of plasma density, potential, and temperature. By calculating the time history of the gun eigenvalue, we observed indications that the Taylor formation paradigm applies. To estimate the spectral characteristics of fluctuations in an FRC, we developed a technique to extract the relevant spectral information using data from the high-resolution multi-point magnetic probe.

  • The DOE-University of Arizona Faculty Development Project on Energy successfully completed a faculty development program. There were three phases of the program consisting of: a three week energy workshop for teachers, participation and cooperation with Students for Safe Energy in presentation of an Alternative Energy Festival at the University of Arizona, and workshops for teachers conducted at Flowing Wells School District. Each of these is described. Attendees are listed and a director's evaluation of the workshop is given.
  • The OJI supported research of J. Ellison has been concentrated in two areas: study of W{gamma} and Z{gamma} production at the Tevatron, which probes the trilinear boson coupling; design, fabrication and testing of silicon microstrip detectors for the D0 upgrade silicon tracking system. The W{gamma} analysis using data from the first D0 run ({approximately}14 pb{sup {minus}1} integrated luminosity) has been completed - J. Ellison and a postdoctoral research working with him (B. Choudhary) were responsible for the muon channel analysis. This analysis is an important test of the Standard Model (SM), since it probes the nature of the WW{gamma} coupling,more » which is related to the W boson magnetic dipole and electric quadrupole moments. Any deviation from the SM value of the WW{gamma} coupling would be an indication of either composite structure of the W or higher order loop corrections involving physics beyond the SM. The analysis has resulted in the world`s most sensitive limits on the WW{gamma} coupling parameters. In addition the author has also worked on an analysis of Z{gamma} production which has yielded sensitive limits on the ZZ{gamma} and Z{gamma}{gamma} couplings. The work on the D0 Silicon Tracker has also made very good progress. The team led by J. Ellison includes two postdoctoral researchers (A. Bischoff and C. Boswell), one graduate student (M. Mason) and three undergraduate students. They have fully evaluated proptotype detectors which were designed at UCR and have completed a detailed simulation study of the detector performance for different strip geometries. The results were used to optimize the design of the final D0 detectors, for which UR has sole responsibility. The author has completed the mask design for the 3-chip barrel detectors and production of the final detectors as now begun.« less
  • This report summarizes the research of the Principal Investigator, his postdoctoral research associates, and his students during the period of the award. The majority of the work concerns the behavior of hadrons containing strange, charm, bottom and top quarks, with a particular focus on the extraction of Cabibbo--Kobayashi--Maskawa matrix elements from experiments performed on such systems.
