Abstract :
This work reports on 2D Particle-In-Cell (PIC) simulations of a Bergeron geometry similar to that used in Ref., focusing on DC multipactor breakdown initiated near a presumed triple-point current source. The simulations in this work use an improved PIC model developed by Taverniers, et al.; additionally, models for space charge, dielectric charging, and secondary-emission are included. Simulation parameters are dielectric insulator angle, gap width, and applied voltage.
