Abstract

Abstract

In most HPM devices, multipactor discharge causes gas ionization and breakdown, and yields plasmas on surface. It would induce the shortening of output HPM pulses, and seriously deteoriate the performance of HPM devices. The metal two-sided multipactor discharge was theoretically analyzed and numerically simulated. Firstly, the dynamics equations, resonant phase, focusing phase, collision potential were introduced and analyzed in theory. Depending on material characteristic of secondary emission, the susceptibility curve of two-sided multipactor discharge was discussed. Secondly, using Monte Carlo method simulating the initial emission energy and angle, the susceptibility curve of two-sided multipactor discharge was studied and discussed compared with the theoretic results. And the relatio
