MVDC circuit breaker hollow cathode plasma PIC modeling using EDIPIC-2D *

We will present recent results of MVDC circuit breaker hollow cathode plasma model Particle-in-Cell model using EDIPIC-2d code, that was previously used for Hall thruster modeling [1]. The code implements explicit leap-frog algorithm, Boris scheme for particle advance and Monte Carlo model of electron-neutral collisions. It accounts for self- consistent electrostatic field and externally defined non-uniform magnetic field. The later feature is useful to study the effect of various possible magnetic field configurations on hollow cathode plasma with the aim of its uniform spreading along the control grid.
