"Time-Resolved Measurement of Energy and Species of an Intense Pulsed Ion Beam"

Abstract

A time‐resolvable Thomson‐parabola spectrometer is developed employing a microchannel‐plate image intensifier, which acts as a high‐speed shutter (∼5 ns) by gating the applied voltage. Using such a spectrometer, we have achieved the measurement of temporal behavior of beam energy for various ion species of an intense pulsed ion beam extracted from a dual‐current‐feed magnetically insulated diode. The energy of protons is found to be in a good agreement with the diode voltage.
