Abstract

An electron gun system for a nanosecond pulse linac has been built and tested. The gun grid is driven with a grid pulser, which consists of an avalanche transistor pulser and parallel triode amplifier. The amplifier is installed in an end hole of the electron gun and provided for power amplification and polarity change of the output pulses of the avalanche transistor pulser. An output pulse of 200 V and 2 ns FWHM was obtained by using the grid pulser of can type transistors. Measurements with a test bench show that the electron gun can deliver 2ns pulse with with currents larger than 3A.
