Abstract
A device is described and test data of a unit for rapid adjustment of the anode voltage of the gyrotron are presented. The unit allows a signal that is proportional to the control to change the voltage at the isolated anode of the gyrotron, which has a capacitance relative to the earth of 100–200 pF, in the range from 0.4 to 1.6 kV with a characteristic time of approximately 1 μs. This allows one to use this unit in the feedback circuit of the phase-locked loop gyrotron frequency. Controlling the frequency and phase of the radiation opens up possibilities for creating powerful highly stable oscillators and synchronizing a large number of gyrotrons, which is relevant, for example, for problems of high-gradient electron acceleration.
