Interaction of Intense Electron Beams with Plasma
Abstract
An exploratory experiment has been performed on the propagation of intense relativistic electron beams through an ionized medium. The beam was produced on the Cornell facility and consisted of a 50 kAmp stream of 350 keV electrons. The initial plasma was produced by a conical theta pinch gun located 1.5 m downstream of the diode and it is estimated that the initial electron density at beam injection was about 10(exp 13) cu cm. Beam propagation was observed photographically, on an X-ray diode at the end of the tube, and on magnetic loops along the tube. Results suggest that the bulk of the beam propagates down the tube at speeds of 1.8 x 10(exp 8) m/sec. The magnetic probe signals indicate that there is appreciable counter streaming current within the plasma volume.
