Abstract
The quasioptical gyrotron (QOG) is developed as a high power source of millimeter-wave radiation. It is designed to produce 4 kW average power from 75-95 GHz using a 20 kV, 1.5 A dc electron beam. A pair of capacitive probes in the drift region are used to measure the average pitch ratio of the gyrating electron beam. The pitch ratio is varied by adjusting the magnetic field at the gun of the intermediate anode voltage. After the beam is characterized, pulsed measurements are performed on output power, efficiency, mode spectrum and output radiation pattern. This tunable QOG will complement existing processing experiments at 2.45 and 35 GHz.
