Abstract
The quasioptical gyrotron (QOG) is under development at the Naval Research Laboratory as a tunable, high power source of millimeter-wave radiation[1]. The present experiment is configured as a gyroklystron where the electron beam is prebunched in an upstream open resonator using an 85 GHz, 1.5 kW extended interaction oscillator (EIO). The gyroklystron typically operates at a beam voltage of 70 kV and a current of 0-10 A. Recent experimental results include 19% electronic efficiency in a single mode at 100 kW output power in a highly overmoded resonator. EIO mode priming, depressed collector, and phase locking results have been obtained, as well as demonstration of a new technique called alpha priming.
