Abstract :
A thermionic gun of the injector linac for SPring-8 is required to generate a different beam pulse width, 1 nsec, 10-40 nsec, 1 μsec. Three types of grid pulsers were prepared to generate a different beam pulse width. The gun uses cathode-grid assembly (EIMAC Y796) and operates up to 200 kV anode voltage. In order to research characteristics of the electron gun, the emission current from the gun was measured by the wall current monitor. In this paper, the pulser system and characteristics of the emission current in region from 30 mA to 19 A are described
