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 100mA with pulse width of 10 ns were obtained.

Key words: Dielectric wall accelerator, Arc discharge, Short pulse high current electron gun, Electric field simulation
