Abstract: Dielectric wall accelerator（DWA）, towards high gradient acceleration field（30 MeV/m–100 MeV/m）, is under development at Institute of Modern Physics. A prototype was designed and constructed to prove the principle. This needs a short pulse high current electron source to match the acceleration field generated by the Blumlein-type pulse forming lines（PFLs）. In this paper, we report the design and test of a new type short pulse high current electron gun based on principle of vacuum arc discharge. Electron beams of 100 mA with pulse width of 10 ns were obtained.
