Experimental study of post-acceleration and transport of a pseudospark-produced electron beam

Preliminary results of post-acceleration and transport experiment of a pseudospark-produced electron beam are presented. The electron beam propagating in a low-pressure gas is accelerated by a simple induction linac system. The beam transport characteristic in the gas filled drift tube is determined and the beam appears to be in the ion-focusing regime. The brightness of the post-accelerated beam is found to be -2/spl times/10/sup 10/ A/(m rad)/sup 2/.<>
