Research of 140 GHz, TE22.6 mode gyrotron for EAST

摘要

The parameters of a 140-GHz TE22.6-mode gyrotron are presented in the article. A single-anode magnetron injection gun (MIG) and the cylindrical resonant cavity operating in the TE22.6-mode are designed for the 140-GHz gyrotron with output power at axial direction. The theoretical efficiency of the gyrotron with operating Voltage 80kV, electron current 40A is about 42%. The gyrotron has been fabricated and will be tested in the future.
