Abstract：
The Micro-Pulse Electron Gun (MPG) is a new type of microwave electron gun that is based on the multipactor discharge. In this paper, the MPG emission currents at different RF power levels are measured and discussed. The steady-state and transient dynamics of multipactor are used to explain the experiment waveforms. The dependence of the multipactor saturation current on the RF gap voltage is also given by the SEEG code. The experimental results agree with the theory qualitatively.
