Abstract

Optimization studies for resonator cavities of quasi-optical gyrotrons have been carried out. If the RF field is limited by local power load on the mirrors, the electronic efficiency can be increased by up to about 10% over the confocal results by using spherical mirrors with g = 1 - d/R close to -1. Optimized nonspherical cavities yield similar results. When output coupling through circular slots is considered, confocal (g = O) as well as more extreme designs near the resonator stability boundary are less favorable and the optimum configurations found are spherical mirrors with g-factors of about -0.3, -0.6 and possibly -0.75
