Theoretic analysis and numerical simulation of dielectric single-surface multipactor discharge

The dielectric single-surface multipactor discharge was theoretically analyzed and numerically simulated. Firstly, the dynamics equations, and the distributions of initial emission energy and angle of secondary electrons were introduced, and the susceptibility curve of multipactor discharge was estimated and analyzed in theory depending on material characteristic of secondary emission. Secondly, Using Monte-Carlo method simulating the initial emission energy and angle, the susceptibility curve of multipactor discharge was studied and discussed compared with the theoretic results, and the relationship was given between the number of secondary electrons and time. Finally, considering electron beam loading and saturation, the particular Monte-Carlo method with fixed time step was adopted in s
