摘　　要：介绍了TLD-3500热释光读出器和GR-100M型热释光剂量片构成的探测器在脉冲硬X射线辐射参数测量中的应用。详细论述了采用滤波荧光法与热释光探测器相结合测量10～100keV的硬X射线能谱的物理思想,在综合考虑了测量环境的具体情况下,设计研制了硬X射线测量系统,建立了热释光探测器对硬X射线绝对能量响应的标定方法。该方法已成功用于脉冲辐射装置"强光1号"的测量,并得到了实测数据。This paper introduces the application of thermoluminescence dosimeter(TLD) which composed by TLD3500 reader and GR100M chips on the measurement of hard Xray pulse energy spectrum. The idea that using Filter Fluorescence Method (FFM) and TLD to measure hard Xray pulse energy spectrum (from 10keV to 100keV) is discussed in details. Considering all the factors of the measuring surroundings, the measurement system of hard Xray pulse has been devised. The calibration technique of absolute energy response of TLD is established. This method has been applied successfully on the radiation parameters measurement of the huge pulse radiation deviceHighpower pulser I. Hard Xray pulse energy spectrum data of the pulser are acquired.
