意大利/荷兰BeppoSAX号航天器的有效载荷包括一套四个X射线集中器，每个集中器的几何面积为124平方厘米，以及位于焦平面上的成像气体闪烁正比计数器探测器。其中一个探测器，低能聚光器光谱仪（LEGS），对能量范围为0.1 - 10 keV的X射线敏感，而其他三个覆盖1.3 - 10 keV的较窄能量范围。为了实现LEGS的扩展的低能量响应，已经开发了一种新型的气体闪烁正比计数器，其省去了传统仪器的单独的漂移和闪烁区域。本文介绍了该仪器的设计、性能及其标定和数据分析系统。
The payload of the Italian/Dutch spacecraft BeppoSAX includes a set of four X-ray concentrators each of geometric area 124 cm(2) together with imaging gas scintillation proportional counter detectors located at the focal planes. One of these detectors, the Low-Energy Concentrator Spectrometer (LEGS), is sensitive to X-rays in the energy range 0.1 - 10 keV, while the other three cover a narrower energy range of 1.3 - 10 keV. In order to achieve the extended low-energy response of the LEGS a novel type of gas scintillation proportional counter has been developed which dispenses with the separate drift and scintillation regions of conventional instruments. The design and performance of the instrument together with its calibration and data analysis system are described here.
