Abstract
The paper presents the tests of a medium-powered 170 GHz gyrotron, which was developed as a master oscillator for frequency locking of megawatt-level sources. In the experiment, the output power of more than 25 kW with about 30% efficiency was obtained in CW mode. With the use of a PLL system, we stabilized this gyrotron frequency and demonstrated the spectrum width of less than 2 Hz, which corresponds to the relative value of about 10 −11 .
