Paper Abstract

A simple, single-stage collector has been tested on the quasioptical gyrotron (QOG) experiment at the Naval Research Laboratory (NRL). This is the first application of a depressed collector to a high-power gyrotron, and was relatively easily accomplished due to the natural separation of the electron beam and the output power in the QOG. Collector efficiencies as high as 50% and overall efficiencies up to 16.1% were observed. The output power reached 431 kW with an overall efficiency of 12.7% and a collector efficiency of 40.7%. The collector efficiency was limited in this experiment due to interception of a portion of the electron beam on an undepressed section of the beam guide.
