Theoretical and Experimental Study of Multipactor Discharge on a Dielectric

Abstract

A review of theoretical and experimental studies of secondary electron emission microwave discharge (multipactor) on a dielectric is presented. The coefficient of microwave power absorption by a single-surface multipactor on a dielectric is found as a function of the incident microwave power and secondary electron emission properties of the dielectric. Results of experimental studies of a single-surface multipactor on a lithium fluoride (LiF) single crystal in a rectangular waveguide are presented and compared with theoretical results. The dependence of the micowave power absorbed by a single-surface multipactor on the incidence angle of microwave radiation is studied numerically and analytically. The influence of the metal waveguide walls on a single-surface multipactor in a parallel-plate waveguide is analyzed. It is shown that, at a sufficiently high microwave intensity, a combined single + double-surface multipactor develops in the region adjacent to the dielectric window.
