A 220 KV Pulsed Cathode Electron Beam Gun System
Abstract
The electron beam gun system consists of a 5 x 25 cm aperture hot cathode gun and a thyratron switched line type high voltage pulse modulator. The gun is cathode pulsed with an operating range of 10 to 40 microseconds at a maximum voltage of 220 kV and maximum peak current of 20 amps. The equipment may be operated at a steady prf up to 150 pps for 15 seconds or in a burst mode of a few pulses each equivalent to the steady state rating. The pulse to pulse voltage stability is achieved at the expense of efficiency by resistive damping the power supply filter, using a resistive load in parallel with the gun and not counting the first low amplitude pulse of each burst.
