The hard X-ray experiment on the Astronomical Netherlands Satellite.
Abstract
The Hard X-ray Experiment flown on the Astronomical Netherlands Satellite is described. The instrument consists of two parts. One is a large-area detector of about 60 sq cm in total area, sensitive in the energy range between 1.5 and 30 keV. Two counters comprise this detector, each collimated 10 min by 3 deg and offset in the narrow direction by 4 min. The other part is a Bragg-crystal assembly consisting of two PET crystals and counters aligned to search for the silicon emission lines near 2 keV. Instrument characteristics and orbital operations are described.
