摘　　要：为了提高多通道软X射线能谱仪的测量精度,2009年在北京同步辐射(BSRF)软X束线源上对多种材料的掠入射平面镜的反射率进行了标定.在标定实验的基础上,对光源的单色性、高次谐波以及源强稳定性、探测器响应一致性和数据采集统计误差等多项不确定因素进行了评估,给出了反射率的修正方法和相应的不确定度分析结果。A key diagnostic for absolute radiation flux and radiation temperature in hohlraum experiments is the Dante soft x-ray spectrometer in which grazing incidence x-ray mirrors are used to diminish the high energy response of the filters.The reflectivities of planar mirrors made of different materials were calibrated in BSRF in 2009.Considering both the influence of the source such as the spectra resolution,harmonic and the attenuation of the source intensity and the influence of the coherence of two detectors responses,we give the corrected mirror reflectivities and the uncertainty,including the statistical uncertainty of the expermental data.
