Pulse-Power-Induced Oscillations of the REX (Relativistic Electron-Beam Experiment) Electron Beam.

摘要

The Relativistic Electron-Beam Experiment pulse power generator is used to produce a 4-MeV, 5-kA, 50-ns electron beam. The beam is produced by a planar velvet cathode. Multiple current rise times are used to examine pulse-power-induced beam oscillations. Diagnostics include a streak camera and high-speed electronic probes for monitoring current and voltage. Correlation between beam oscillations and TE/TM cylindrical cavity modes in the anode-cathode gap is examined. 2 refs., 9 figs. (ERA citation 14:022948)
