BUCKSHOT Benchmarking and Delphi Applications

摘要

The code BUCKSHOT which is an electrostatic particle simulation code has been developed and is being used at Sandia to study effects of the ion hose instability on electron beam propagation in the Ion-Focused Regime (IFR). The code solves the equations of motion in the plane transverse to the direction of propagation. First, we consider benchmarking the code against a problem for which the exact solution is known, namely linear ion hose growth in the limit of a rigid beam-channel system. We then consider beam propagation in the absence, and in the presence, of an external transverse magnetic field, for Delphi parameters. 4 refs. (ERA citation 13:002115)
