| Abstract: | Whether the excellent properties of free electron laser can be brought into practice,it would ultimately depend upon the fact that the laser could be made compact.This paper proposed a improved and small scale control system and accelerator for FEL, and introduced the compact Raman FEL.In control system,a new designed three channel time delay trigger utilized to trigger Marx generator to produce a high voltage pulse.The electron beam source is a key component in our system.We employed a pseudospark discharge device to substitute the diode.The devise can obtain 10kA discharge current and current pulse half width of 640ns at 300kV discharge voltage,the electron beam flow can achieve greater than 1kA. |
