We develop and study for the first time a high-current Ka-band gyrotron having an electron-optical system with magnetic compression, which ensures the formation of a helical electronc beam with an energy of 500 keV, a current of 2 kA, and a pitch factor of about 1.0. Generation of the radiation with a power of 35–40 MW and a pulse duration of about 5 ns is achieved at the TE−3, 2 and TE−4, 2 modes with frequencies of 30.6 and 35.7 GHz, respectively.
