摘要：

Developments of two types of the electron gun are presented. One is a compact DC electron gun using Field Emitter Array (FEA) as the cold cathode, the other is a photoinjector which outputs sub-pico second electron beam pulse. The FEA electron gun achieved to producing a 2 mA/50 kV electron beam. The photoinjector experiments revealed an exotic space-charge effect on the ultra-shot electron beam pulse. © 2014 The Institute of Electrical Engineers of Japan.
