Based on the study of explosive emission, the dielectric enhancement electric-field emission model is brought forward, and the metal-dielectric complex cathode material is manufactured. Based on the investigation of surface-flash explosive emission, the graphite-carbon fiber complex cathode is manufactured. Then the experiments are developed respectively, and the result shows the electron emission density of these two complex cathode materials is more than 17 kA/cm2, and their lifetime is more than 105 pulses．
