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

Abstract

We have developed a theoretical analysis of the current scaling issues of a negatively biased probe in a plasma wake. The 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 number 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.
