ON THE PROPAGATION OF HIGH-CURRENT BEAMS OF RELATIVISTIC ELECTRONS IN GASES

Abstract
The transit time of high current beams of relativistic electrons (40–50 kA, 350 keV) through an air filled (0.2–2.5 Torr) drift tube has been measured. It is longer than expected, even allowing for the loss of beam front electrons and for orbiting of the electrons in the beam self‐magnetic field. Also, a pressure‐dependent nonuniformity in the beam motion was observed which may account for this delay.
