60 GHz Gyrotron Development Program. Quarterly Report No. 20, April-June 1984

摘要

The objective of this program is to develop a microwave oscillator capable of producing 200 kW of c-w power at 60 GHz with high purity of the output mode. The calculations for the design of the 4-inch diameter collector were concluded. The final design predicts 96.8% TE sub 02 mode output and is designed to allow a retrofit replacement of the collector on existing tubes. Work during the quarter emphasized the testing of the c-w tube X-7. Operation of the tube is reported for both pulsed and c-w operation. Output mode purity was measured at 95% TE sub 02 . The tube was operated for about 40 minutes with c-w power output over 200 kW. (ERA citation 10:015462)
