Abstract

Abstract

Particleincell algorithms for computing current density and explosion electron emitting from cathode are briefly introduced. The current density algorithm which satisfies charge and current continuity equation, can avoid complex Poisson adjustment and can be used in simulation of physics problem with complex boundarys. Based on the algorithms of computing current density, a new model for explosion electron emission from conducting boundary surfaces is described. The new model is proved out by results of particle simulations of vacuum diode.
- particleincell simulation,
- current density algorithm,
- explosion electron emission,
- charge and current continuity equation
