XRD灵敏度在同步辐射源上的绝对刻度
-
摘要: 在BEPC同步辐射的3B1束线上，利用多层镜分光，获得了单色性较好，强度较高的软X光光源。采用美国进口的AXUV-100Si光二极管作为二级标准，对XRD探测器和滤片进行绝对刻度，获得了各种阴极XRD的灵敏度，其结果与LLNL的实验结果吻合，并对实验结果作了分析。Abstract: The monochromatic X –ray source was obtained using multilayer mirror on the BEPC –SR. The Sensitivity of X –ray diodes (XRD) and thickness of filters were calibrated using AXUV-100 silicon photodetector as the secondary standard. The experimental results of XRD sensitivity are consistent with LLNL experimental results.
