摘要
报道了软X光能谱仪探测元件的能量响应曲线标定工作 .实验利用北京同步辐射装置 -3W 1B束线及反射率计靶室 ,在束流 4 0— 80mA、贮存环电子能量 2 2GeV专用光运行模式下 ,在 1 50— 1 50 0eV能区的四个能段 ,做了铝阴极X射线二极管、滤光片及掠入射平面反射镜能量响应标定实验 .通过实验数据比对及分析 ,最终给出X射线二极管在不同能量段最大可能的测量误差范围 .
The calibration of the energy response of the detection elements for soft X ray spectrometer is reported. The calibration is carried out Beamline 3W1B of Beijing Synchrotron Radiation Facility with beam intensity 40\_80mA at electron energy 2.2GeV,using vacuum chamber of reflectometer on An AXUV 100 silicon photodiode is used as the source intensity absolute monitor in the photo energy rang 150—1500eV. The energy response curves for X ray diode (XRD) quantum efficiency,filter transmittance and grazing planar mirror reflection efficiency have been measured. Finally,the possible maximum errors of the XRD at different energies are given based on these experimental data.
