Abstract The Hard X-ray Experiment flown on the Astronomical Netherlands Satellite is described. The experiment consists of two parts. One is a large- area detector of about 60 cm² total area, sensitive in the energy range 1.5- -30 keV. Two counters comprise this detector, each collimated, by 10'times3degree and offset in the narrow direction by 4'. 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. (AIP)
