GE Proposed Run A

GE PROPOSED RUN A: Ng = 3e14 cm-3, I = 2.85 mA

This problem using the Lawler and Kortshagen cross-sectional data was run for 100 microsecs. Equilibrium was reached at about 15 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 = 1.64e9/cc. The following is a link to the input file: Input File.
