Abstract
A guided field is an important part for focusing the intense beam in Raman free electron laser. A new electron beam source with high brightness of 1012A/(m rad)2 based on a pseudospark discharge was developed [1]. Numerical simulation showed that the guided field for compact free electron lasers could be removed using the new beam source. An electron beam with 12 kA current and 300 kV voltage was obtained. Self-pinch effect of high current beam was observed, the beam propagates 75 cm with constant diameter of 1.5 mm without guided field.
