Development and experimental tests of 250W/526 GHz/CW second harmonic gyrotron

In the gyrotron operating at the second harmonic of the gyrofrequency at a frequency of 526 GHz, radiation power of 250 W was obtained in the continuous wave generation mode. The indicated value is several times higher than all known world analogs. Experimental results open new perspectives of gyrotron application for spectroscopy, where both high frequency and high-power are needed.
