Heliosphere Instrument for Spectra, Composition and Anisotropy at Low Energies (HI-SCALE)

The HI-SCALE (LAN) Experiment makes measurement of interplanetary ions and electrons. This will advance the understanding of the physical processes involved in the solar control of low energy ions and electrons in a region of the heliosphere never before studied.

Operational issues

Spiral motor heaters are occasionally used to close the telescope covers during detector calibrations.
