Frequency response of multipactor discharge

Abstract
This paper analyzes the frequency response of a two-surface multipactor in a rf circuit. An equation for the frequency band in which steady state multipactor can occur is derived in terms of the secondary emission properties of the surface, the quality factor Q of the rf circuit, and the operating voltage. The steady-state multipactor current is also derived, and is shown to be in excellent agreement with numerical computations that follow the temporal evolution of the multipactor discharge.
