A spiral strip transformer type electron-beam accelerator

Abstract

An electron-beam accelerator, which consists of a primary storage capacitor system, an air core spiral strip transformer, water Blumlein line of water dielectric, and a field-emission diode, is described. The experimental results show that the diode voltage is more than 400 kV, electron beam current is about 40 kA, and the pulse duration is more than 80 ns. This accelerator is very compact and works stably and reliably.
