Multichannel Neutral Atom Energy Spectrometers for Plasma Diagnostics

Multichannel neutral atom energy spectrometers for energies of 0.3-10 keV for use on fast pulsed plasma experiments are described. The spectrometers consist of a gas stripping cell, a fixed or variable magnetic prism, and a row of scintillator-photomultiplier detectors. Calibration, data analysis, and some operating experience are described.
