3.2 MILLIMETER WAVE OSCILLATOR

Progress is reported of the development of a permanent-magnet-focused, 10 kW, pulsed, distributed interaction klystron which oscillates at 93.75 GHz and which has been both environmentally and life tested. Efforts are continuing toward the final design of the parmanent-magnet package. The mechanical tuning assembly for the output coupler has been improved, and the electron gun assembly has been made more rugged. Most of the required parts have been received, and construction of the various test vehicles has begun. An experimental tube containing a shorter cavity structure is almost completed. The fabrication has begun of another short pulse modulator needed for the test and evaluation of the tubes. (Author)
