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.
Claims25
A process comprising:
- raising a filament voltage of a gyrotron to a standby voltage;
- setting the filament voltage to the standby voltage plus a current offset voltage before pulsing the gyrotron;
- increasing 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;
- and
- analyzing a beam power of the gyrotron and adjusting the filament voltage to bring a beam current within a range.
A process comprising:
- monitoring one or more gyrotron variables;
- and
- adjusting a voltage supplied to a filament of a gyrotron to regulate a temperature of a cathode of the gyrotron and thereby control a power output of the gyrotron.
A system comprising:
- a gyrotron;
- and
- a processor coupled to the gyrotron, the processor comprising:
- a warm-up ramp processor configured to raise a voltage of a gyrotron filament to a standby voltage;
- a standby processor configured to set the voltage of the gyrotron filament to the standby voltage and an offset;
- a firing processor configured to fire a pulse to the gyrotron filament;
- and
- a boost processor configured to raise the gyrotron filament voltage to a boost voltage after the pulse begins.
