利用北京同步辐射3B3中能束线,在国内首次实现了XRD X射线探测器灵敏度在2—6keV能区的标定,灵敏度的不确定度小于7%．另外中能束线的应用还极大地提高了滤片厚度的标定精度,其厚度的不确定度小于3．6%．
Using Beijing Synchrotron Radiation 3B3 beamline, the calibration of XRD X-ray detector sensitivity in the 2-6 keV energy region was first realized in China with the sensitivity uncertainty of less than 7%. In addition, the application of medium beamline also greatly improves the calibration accuracy of filter thickness, the uncertainty of its thickness is less than 3.6%.
