A time resolved spectrometer for high intensity relativistic electron beams

Abstract

A spectrometer system designed to measure the time‐dependent kinetic energy of electrons from high current pulsed relativistic beam accelerators is described. The spectrometer, consisting of a three‐element vacuum Compton diode, is simple, rugged, and self‐driving. Calibration data are presented covering the energy range of 150 keV to 16 MeV. Applications and limitations of the spectrometer are discussed.
