The precipitating and upflowing ion measurements contribute to the overarching goal of the TRACERS mission. ACI is a toroidal top-hat electrostatic analyzer on a spinning platform that provides full angular coverage with instantaneous 22.5 degrees x approximately 6 degrees angular resolution for a single energy step. ACI has an ion energy range from approximately 8 eV/e to 20,000 eV/e covered in 47 logarithmic-spaced energy steps with fractional energy resolution of approximately 10%. It provides reasonably high cadence (312 ms) measurements of the ion energy-pitch angle distribution with good sensitivity and energy resolution, enabling detection of cusp boundaries and characterization of cusp ion steps."
