Abstract
Results from a quasioptical gyrotron experiment with a 20–28-cm mirror separation are presented showing operation from 95–130 GHz at powers up to 148 kW and output efficiencies up to 12%. The output coupling could be varied from 0.4%–3% by changing the mirror separation and operating frequency. Efficiency optimization by variation of output coupling and by tapering the magnetic field has been demonstrated and regions of single-mode operation at powers up to 125 kW have been characterized.Keywords
