FREQUENCY-RESPONSE OF MULTIPACTOR DISCHARGE

This paper analyzes the frequency response of a two-surface multipacto r in a rf circuit. An equation for the frequency band in which steady state multipactor can occur is derived in terms of the secondary emiss ion properties of the surface, the quality factor Q of the rf circuit, and the operating voltage. The steady-state multipactor current is al so derived, and is shown to be in excellent agreement with numerical c omputations that follow the temporal evolution of the multipactor disc harge.
