Final Technical Report on DOE Junior Faculty Development Award

[摘要] 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 ??m) 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.
