Abstract :
This work reports on 2D Particle-In-Cell simulations focusing on DC multipactor breakdown initiated near a presumed triple-point current source. Models for space charge and dielectric charging are included. Simulation parameters include dielectric insulator angle, gap width, and applied voltage. Breakdown voltage as a function of angle is presented, and simulations are compared to theory and experiment.
