Auroral Ion Mass/Energy Spectra

This data set contains ARCAD-3 Spectro Auroral Ion Mass/Energy Spectra. The ARCAD-3 Spectro suprathermal ion spectrometers, ION1 and ION2 measured the abundance of ionospheric (H+, He+, O+) and solar wind/magnetospheric ion species (H+, He++), from ~10 eV to ~14 keV/charge and from 1 to ~32 AMU, in two different viewing directions, ~60° and ~120° pitch angle. The basic design included a collimator followed by a retarding potential analyzer (RPA), the electrostatic energy analyzer (cylindrical). Subsequent...
