This paper summarizes the design and performance of the hard X-ray detector constructed for the ASTRO-E satellite. The detector utilizes the GSO/BGO well-type phoswich counters in a compound-eye configuration to achieve an extremely low background level of a few × 10-5counts s-1 cm-2keV-1 [1]. The GSO scintillators installed in the BGO active shield wells are sensitive to 30-600 kev photons, while the 2-mm-thick silicon PIN diodes, placed in front of each GSO crystal, cover the 10-60 kev energy band with a spectral resolution of ∼3.5-keV full-width at half-maximum. The design goals, of both low background and high energy resolution, in the hard X-ray bands were verified through the preflight calibration experiments.
