Abstract :
Based on the study of explosive emission, the dielectric enhanced electric-field emission model is brought forward, and the metal-dielectric complex cathode material is manufactured. Based on the investigation of surface-flashover explosive emission, the graphite-carbon fiber complex cathode is manufactured too. Then the experiments are developed respectively, and the results show the electron emission density of these two complex cathode materials is also more than 17 kA/cm2, and their lifetime is excess 105 pulses.
