Abstract

Modulation of the beam current has been observed during ion focused regime (IFR) transport of a high-power relativistic electron beam immersed in a low-density background plasma. In this experiment, a 1.6-MeV, 1-kA, risetime sharpened electron beam is propagated on a KrF excimer-laser-produced IFR channel in TMA gas which is immersed in a low-density plasma filled transport tube. Experimental measurements demonstrating modulation of this high-current relativistic electron beam near the background plasma frequency are presented.<>
