摘　　要：位置灵敏探测器(Position sensitive device,PSD)是一种利用光电二极管表面电阻的光电子位置传感器,具有高速度、高分辨率、可靠性好等优点。本文描述了将PSD用于X射线条件性能测试的结果,给出了基于PSD的X射线光束位置探测器(X-ray beam position monitor,XBPM)的一个具体设计方案,并进行了相应估算,初步表明了其可行性。Position sensitive device (PSD) is an optoelectronic position sensor utilizing photodiode surface resistance, features high-speed response, high position resolution and high reliability. The performance of PSD under X-ray was tested. Based on this test, an X-ray beam position monitor (XBPM) utilizing PSD was designed, some calculation supporting the design was also performed.
