Time-Resolved Current, Current-Density, and Emittance Measurements of the PHERMEX Electron Beam

摘要

The PHERMEX electron-beam pulse is a burst of ten 3.3-ns micropulses separated by 20 ns. Typical accelerator operating parameters produce a mean beam micropulse energy of 26 MeV with peak current of 300-500 A. The purpose of this work is to present experimental measurements of the current, current density, and emittance of a single PHERMEX micropulse. This experiment is part of an effort to completely characterize the PHERMEX electron beam. Understanding the electron-beam parameters is necessary for machine upgrade as related to flash radiography and for both present and future electron-beam experiments. (ERA citation 10:034418)
