| 摘 要： | 在北京同步辐射装置上，通过对应用于惯性约束聚变（ICF）实验的平面镜反射率的进一步研究，提高了辐射温度的测量精度。进行了对软X射线平面镜反射率的测量、反射镜的清洗、反射率的模拟计算，证明影响反射率变化的主要因素是平面镜的安装角度和沾污。实验结果表明:平面镜的沾污主要来源于ICF实验中的油沾污，采用射频辉光放电清洗非常有效。

| Abstract: | Soft X-ray mirror used in inertial confinement fusion (ICF) experiments have been preformed at the 4B7B beam-line of Beijing Synchrotron Radiation Facility (BSRF). The main factors influencing the mirror reflectance were investigated and confirmed to be the contamination and the installation angle of mirrors. Simulation of the reflectance of contamination mirrors confirms the contamination is the carbon and oxygen from oil in ICF experiments. The contamination can be effectively removed by a radio-frequency glow discharge treatment for mirrors. The reflectance of mirrors which is improved after cleaning process is found to be in good agreement with the calculation results. |
