摘要
介绍了中国计量院单能X射线实验室开展的单能X射线标定装置和探测器标定方法研究。已经建立的单能X射线标定装置能量范围可覆盖5~300 keV,为我国空间科学卫星的星载探测器提供了能量线性、探测效率、位置响应和角度响应等性能指标的地面标定。正在标定的卫星项目有:SVOM、GECAM和HXI等科学卫星的星载探测器。
This paper introduces the research on the monoenergetic X-ray calibration device and detector calibration method carried out by the Monoenergetic X-ray Laboratory of NIM.The energy range of the established monoenergetic Xray calibration device can cover 5~300 keV,which provides the ground calibration of performance indicators such as energy linearity,detection efficiency,position response,and angular response for space-borne detectors of space science satellites in China.Satellite projects being calibrated include spaceborne detectors for scientific satellites such as SVOM,GECAM,and HXI.
