在北京同步辐射装置(BSRF)上建立了国内唯一的软X射线光学实验平台,主要用于惯性约束聚变(ICF)激光等离子体诊断用探测元器件的精密标定技术研究。硬件方面主要包括两条不同能区的单色聚焦X射线光束线(能量范围0.05-6 keV)、高精度软X射线综合测试分析装置、软X射线标准探测器电离室系统及若干探测器标定装置等,软X射线(0.05-1.5 keV)和中能X射线(1.2-6 keV)两条光束线各项性能指标均达到或优于原设计指标。一大批ICF实验用的探测器在实验平台上进行了标定,主要包括X射线探测器(XRD)、反射镜和多层膜、透射光栅、电荷耦合器件(CCD)等,还包括一些新的探测元器件,如:晶体、成像板等,这些探测元器件被用于ICF实验中,取得大量的成果。该平台在光学、天文、材料、计量和Z箍缩实验等领域也得到了广泛的应用。

The soft X-ray experimental platform is constructed for accurate calibrating detector of inertial confinement fusion (ICF) on Beijing synchrotron radiation facility (BSRF).It is the only one in our country.The platform mainly consists of two synchrotron radiation beamlines (energy range:0.05-6 keV),high precision reflectometer,X-ray standard detector of ion chamber,and some calibrating devices for the detector.The soft X-ray beamline (4B7B) andmiddle X-ray beamline(4B7A) are constructed successfully.Their targets and parameters are achieved and excel the original designs.A lot of detectors are calibrated with the platform.They are X-ray detector (XRD),mirror and multilayer,filter,transmission grating,charge coupled device (CCD),and other new type of detecting elements and devices,such as crystal and image plate,with which lots of achievements are obtained in ICF experiments.The platform also has many applications in other fields such as optics,material,astronomy,metrology,and Z-pinch′s detector calibration,etc.
