This presentation reviews recent progress of Russian physicists in developing electronic devices the gyroresonance type, which are so far most advanced sources millimeter microwaves. It deals with concept gyrotron as a device operating at higher volume resonator modes built-in quasioptical converter output radiation into wave beam. That made it possible to create comparatively simple and reliable long-pulse quasicontinuous power level 0.5 MW frequency band 30–160 GHz. Analysis principal problems projects for continuous-wave (CW) gyrotrons near 1 (choice an mode, requirements electron beam, peculiarities converters) is included, well results model experiments. For amplifying wavelength gyroklystrons, several hundreds kW 35 GHz, up 65 94 GHz were also achieved. Some modifications material processing special research described.
