High-Current Beam Transport Experiments Using Foil Focussing

Abstract

Numerous applications of electron beams require transport, centering and steering of relativistic, high current electron beams (REB). One method which has application to all of these objectives involves the use of conducting grounded foils transverse to the beam direction. 1 2 This technique allows self-pinched stable transport of high current REB's in vacuum, with currents in excess of the longitudinal space charge limit. Beam centering is accomplished via the image currents in the tube walls which provide a current dependent centering force for the electron beam.
