Ohmic Effects in Quasioptical Resonators

Abstract

Several properties of the Fabry-Perot-type open resonator used in the quasioptical gyrotron (QOG) and the quasioptical induced resonance electron cyclotron (IREC) maser are derived. The electric fields of the normal modes are given for the general case of the resonator axis tilted with respect to the direction perpendicular to the electron beam axis. The ohmic quality factor and the power dissipated in the mirrors is derived, as is the energy stored in the resonator. The time dependence of the mirror heating, useful for pulsed experiments, is also derived. The formulae are applied to an example of current relevance, the IREC maser resonator.
