XRD探测器和滤片在北京同步辐射3B3中能束线上的标定

Calibration of XRD Detector and Filter on the 3B3 Medium Energy X-Ray Beam in BSRF

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%．

The sensitivity of XRD detector in 2.1-6.0keV energy range has been calibrated on the 3B3 medium energy X-ray beam at the BSRF for the first time in our country, and the uncertainty is less than 7%. In addition, the calibration precision of filter thickness has been improved by using the 3B3 medium energy X-ray beam, and the uncertainty of the filter thickness is less than 3.6%.
