Abstract
A system to regulate gyrotron power is configured to raise the filament voltage of a gyrotron to a standby voltage, then set the filament voltage to the normal standby voltage plus a current offset voltage before pulsing the gyrotron. The system is further configured to increase the filament voltage to a boost voltage that is higher than the standby voltage, thereby inducing a temperature increase in the cathode that offsets the cooling effect of radiating. The system is also configured to analyze a beam power of the gyrotron and adjust the filament voltage to bring a beam current within a range, and reduce the filament offset to zero such that the filament voltage is equal to the standby voltage.
