GE PROPOSED RUN J: Ng=1e14 cm-3, I=100 mA


This problem using the Lawler and Kortshagen cross-sectional data was run for 17 microsecs. Equilibrium was reached at about 7 microsecs as can seen from the Average Density(t) and Ez(t) diagnostics below. On a Pentium III 600 MHz machine this run would take about 4 hours to reach equilibrium. The simulation starts off with initial Bessel function electron and ion density profiles with axial density = 8e9/cc. The following is a link to the input file: Input File.
