A new telescope consisting of three two-dimensional position-sensitive silicon detectors which can measure the linear energy transfer (LET) distibution over the range from 0.2 to 400keV/mum has been developed as a real-time radiation monitor in manned spacecraft. First, the principle of LET measurement and its design method are described. Second, suitable electronic parameters for the LET measurement are experimentally determined. Finally, the telescope performance is investigated by using relativistic heavy ions. The first-flight test of this type of telescope on the US Space Shuttle (STS-84) is scheduled for May 1997.

研制了一种由三个二维位置敏感硅探测器组成的新型望远镜，可测量0.2 ~ 400 keV/mum范围内的线能量传递（LET）分布，可用于载人航天器的实时辐射监测。首先介绍了LET测量原理及其设计方法。其次，实验确定了合适的电子参数的LET测量。最后，利用相对论重离子研究了望远镜的性能。这种望远镜定于1997年5月在美国航天飞机（STS-84）上进行首次飞行试验。
