34 GHz, 45 MW pulsed magnicon for accelerator applications

A high efficiency, high power magnicon to operate at 34.272 GHz has been designed and built as a microwave source to develop RF technology for a future multi-TeV electron-positron linear collider. To develop this technology, it is necessary to test accelerating structures, RF pulse compressors, RF components, and to determine limits from breakdown and metal fatigue. The tube is designed to provide a peak output power of /spl sim/45 MW in a 1 microsecond pulse, with a gain of 55 dB, using a 500 kV, 220 A, 1 mm-diameter electron beam. The status of the tube itself as well as the near-term experimental program is presented.
