Development program for a 200 kW, c-w gyrotron. Quarterly report No. 17, July-September 1983

The objective of this program is the design and development of a millimeter-wave device to produce 200 kW of continuous wave power at 60 GHz. The device, a gyrotron oscillator, will be compatible with power delivery to an electron-cyclotron heated plasma. Smooth control of rf power over a 17 dB range is required, and the device should be capable of operation into a severely time-varying load mismatch. Test results on S/N 1B, SN 2A and SN 3 are presented.
