Summary:Summary form only given. The CW/263 GHz gyrotron is developed at IAP RAS for future application as microwave power source in DNP/NMR spectrometers. The new experimental facility with computerized control was built to test this and subsequent gyrotrons. The maximum power up to 1 kW in 15 kV/0.4A operation regime has been obtained. The power about 10W, which looks enough for spectroscopy, was realized in low current 14 kV / 0.02A regime. The possibility of frequency tuning with variation of coolant temperature about 4 MHz / 1 degree was demonstrated. The spectrum width of the gyrotron is about 10 -6 . Next tubes with frequencies 527 GHz and 790 GHz are under development.
