Abstract
The output frequency of Gyrotron FU IV is stabilized by stabilizing high voltage power supplies for gun anode and cathode. In addition, we apply the phase lock control of beam energy to achieve higher stabilization of the frequency. A cavity is designed for high purity mode and installed in Gyrotron FU VA. The gyrotron emits many modes with high purities. For almost all modes, the purity is higher than 90 percent.
