REX, A 5-MV Pulsed-Power Source for Driving High-Brightness Electron Beam Diodes

The relativistic electron-beam Experiment, or REX accelerator, is a pulsed-power source capable of driving a 100-ohm load at 5 MV, 50 kA, 45 ns (FWHM) with less than a 10-ns rise and 15-ns fall time. This paper describes the pulsed-power modifications, modeling, and extensive measurements on REX to...

Zusammenfassung:The relativistic electron-beam Experiment, or REX accelerator, is a pulsed-power source capable of driving a 100-ohm load at 5 MV, 50 kA, 45 ns (FWHM) with less than a 10-ns rise and 15-ns fall time. This paper describes the pulsed-power modifications, modeling, and extensive measurements on REX to allow it to drive high impedance ( 100s of ohms) diode loads with a shaped voltage pulse. A major component of REX is the 1.83-mdiam x 25. 4-cm-thick Lucite insulator with embedded grading rings that separates the output oil transmission line from the vacuum vessel that containing the re-entrant anode and cathode assemblies.
