Abstract :
A transportable power supply system has been designed to operate gyrotrons at varying locations. The system is designed to operate with an output of -100 kV at 50 A during CW (continuous wave) operation (5 MW). Components that have been modified for the higher power operation, as well as the transportability, are the raw DC power supply and the modulator/regulator. A newly designed capacitor bank, with a crowbar, has been installed as an intermediate element between the power supply and the modulator/regulator, using existing capacitors. When the time comes for the system to be moved to a new location, the system breaks down into six large pieces that can be reassembled in a week. The entire system is controlled by a CAMAC-based computer control system that can easily be tied into the test of the gyrotron subsystems or can be used as a stand-alone system running the power supply system itself. The power supply system will first be at Varian Associates, and it will be used for the development of high-power microwave tubes for the US DOE Gyrotron Development Program
