Abstract

Contrary to single particle analysis of multipactor discharges, experimental results show that application of a magnetic field parallel to the RF electric field can result in a significant reduction of the breakdown threshold voltage1. One explanation is that diffusion of electrons out of the region of interest results in higher breakdown thresholds without a confining magnetic field. However, the size of the reduction experimentally observed is not typically duplicated in numerical simulations. While these simulations take into account electromagnetic field structure and device geometry, precise secondary electron behavior is difficult to match and general curves for secondary electron yield and emission energies are typically used.
