Astro-E Hard X-ray Detector
Abstract
Astro-E HXD consists of 16 well-type GSO/BGO phoswich counters with imbedded thick silicon PIN diodes, 20 BGO anti-coincidence counters, analog electronic circuitry for signal amplification and filtering, and data acquisition and control electronics. The PIN diodes record hard X-rays in the lower energy range ( ~ 10 - 50 keV) and the well-type phoswich counters in the higher energy range ( ~ 40 - 600 keV). The anti-counters serve to reduce background and also as a monitor for gamma -ray bursts and X-ray transiens. The HXD is characterized by a wide energy range coverage (10--600 keV), a collimated narrow field of view ( ~ 0.(deg) 5 up to 200 keV, ~ 4.(deg) 5 above 200 keV) and a very low background of ~ (1-5) x 10(-5) cm(-2) s(-1) keV(-1) . We expect the HXD to become the most sensitive cosmic hard X-ray detector ever put into orbit.
