Abstract: The parameters of a 140GHz 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 140GHz 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 tested. In short pulse operation (~70 microseconds) an output power of ~150kW with frequency of 140.36GHz is obtained in operating voltage 70kV, electron beam 20A.
