Abstract

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.
