Temporal study of dual frequency single surface multipactor by multiparticle Monte Carlo simulations

This work investigates the temporal physics of multipactor discharge on a single dielectric surface by one-dimensional multiparticle Monte Carlo (MC) simulator with adaptive time steps. The study shows that the presence of a second carrier frequency of the rf electric field changes the saturation level and temporal oscillation pattern of the normal surface field. It is found that the instantaneous normal surface field and the multipactor electron population remains at a lower value for a longer duration within an rf period for dual frequency operation than for single frequency operation.
