      Instrument Overview
      ===================

      (excerpted from: [LANZEROTTIETAL1992])

      Abstract. -- The Heliosphere Instrument for Spectra,
      Composition, and Anisotropy at Low Energies (HI-SCALE) 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 (i.e., coverage of essentially 4 [pi] ster)
      from the spinning spacecraft. Ion elemental abundances are
      determined by a delta 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 analyser (channels spaced logarithmically) for more
      detailed spectra. The instrument weighs 5.775 kg and uses
      4.0 W of power. Some initial in-ecliptic measurements are
      presented which demonstrate the features of the instrument.
