The design principle of the electron gun is studied, the design procedure of the E-GUN is mastered, the theoretical design of the electron gun is completed, and a focusing electron gun with reducing the heat radiation of the filament is designed. The gun can produce 600mA DC electron beam under 20kV DC high voltage, and the cathode adopts the hot LaB6 between tungsten wires. In addition, a 20kV, 1A high-power DC high voltage (and its protection circuit) system has also been established. Isolation transformers, vacuum systems and measurement systems (high-power 20kW water-cooled Faraday cup and envelope measurement) have been established.
