本文概述了ASTRO-E卫星硬X射线探测器的设计和性能。该探测器采用复眼配置的GSO/BGO阱型phoswich计数器，以实现极低的本底水平，为几个/spl倍/ 10/sup-5/计数s/sup-1/ cm/sup-2/ keV/sup-1/。安装在BGO有源屏蔽威尔斯井中的GSO振荡器对30-600 keV光子敏感，而放置在每个GSO晶体前面的2 mm厚硅PIN二极管覆盖10-60 keV能带，光谱分辨率为/spl sim/3.5 keV半峰全宽。通过飞行前的标定实验，验证了硬X射线波段低本底和高能量分辨率的设计目标。
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 /spl times/ 10/sup -5/ counts s/sup -1/ cm/sup -2/ keV/sup -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 /spl sim/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.
