Advanced Detector Development, Laboratory Simulations, Diagnostic Development, and Data Analysis on Wake Physics

Abstract

We have performed a number of experiments and have developed a theoretical analysis of the current scaling issues of a negatively biased probe in a plasma wake. The end product of the laboratory research performed in the large vacuum chamber JUMBO at Phillips Laboratory can be found in the associated publication. Theoretical assumptions have been analyzed qualitatively and quantitatively by the use of the POLAR computer code. For a plasma with a constant beam energy, the analysis shows that the I-V collection characteristics are unaffected by Mach variations for Mach numbers above the value of two. For the same case, the current was found to scale with the 3/7 power of the density.
