Frequency response in multipactor discharge

Summary form only given, as follows. There is a resurgence of activities on the analysis of multipactor discharge, which is a medium to low voltage phenomenon in microwave cavities, windows, satellite RF payloads, and accelerator structures. In this paper, we extend our previous model to examine the frequency response of the multipactor discharge in an RF circuit, with special emphasis on the effects of loading and detuning of the circuit. We have calculated analytically the frequency band in which a steady state multipactor could occur. The saturation level is also calculated. These results are found to be in excellent agreement with those obtained from numerical simulations. In general, the frequency band in which multipactor would occur narrows as the quality factor Q increases. We have recently initiated a study of multipactors on insulators, preliminary results are presented.
