DATA_SET_DESCRIPTION Data Set Overview ================= This data set consists of HISCALE W ion counts from the Ulysses Jupiter encounter 1991-Dec-31 to 1992-Feb-16. This includes 1 hour averaged inbound cruise data (1991-12-31 to 1992-02-01), and 15 minute averaged encounter data (1992-02-02 to 1992-02-16). The Heliosphere Instrument for Spectra, Composition, and Anisotropy at Low Energies is designed to make measurements of interplanetary ions and electrons throughout the entire Ulysses mission. The ions (Ei > 50 keV) and electrons (Ee > 30 keV) are identified uniquely and detected by five separate solid-state detector telescopes that are oriented to give nearly complete pitch-angle coverage from the spinning spacecraft. Ion elemental abundances are determined by a del E vs E telescope using a thin 5 micrometer front solid state detector element in a three element telescope. Experiment operation is controlled by a microprocessor-based data system. Inflight calibration is provided by radioactive sources mounted on telescope covers which can be closed for calibration purposes and for radiation protection during the course of the mission. Ion and electron spectral information is determined using both broad-energy-range rate channels and a 32 channel pulse-height analyses (channels spaced logarithmically) for more detailed spectra.
