摘要
介绍同步辐射 (SR)在惯性约束聚变 (ICF)研究中的应用 .北京同步辐射光源 (BSRF)在专用光运行模式下 ,束流强度 35— 110mA ,贮存环电子能量 2GeV .标定前 ,首先采用 10 0 0PL mm透射光栅作色散元件 ,对光源进行单色性研究 ,用面阵软X光CCD对光斑进行均匀性研究 .在 3W1B束线上 ,可用能区 5 0— 15 5 0eV ,通过不同材料前置滤片抑制高次谐波 ,获得单色性好于 95 %的单色光 .几年来 ,对十余种ICF实验诊断用软X光探测元器件及设备进行了能量响应绝对标定 .大量实验标定数据被用于ICF实验诊断 。
In this paper the calibrations of different soft X-ray detector elements used in experiment diagnostics of Inertial Confinement Fusion (ICF) with Synchrotron Radiation is reported. Beijing Synchrotron Radiation Facility used special operation type with beam current 35—110mA, the storage ring electron energy 2GeV, photon energy region 50—1500eV. The performance of the light source is studied by transmission grating and face array CCD system. We divide 50—1500eV energy region in seven energy section through different material prefilter with monochromaticity than 95%. The energy response of different soft X-ray detector elements are calibrated. The calibration results are used in ICF data analysis, which secures the accuracy of data treatment.
