| Abstract: | Fluorescence screen(FS) is an important part of beam position monitor(BPM) for locating light spot of beamlines in Shanghai Synchrotron Radiation Facility(SSRF).In this work,the photoluminescence characteristics of Ce:YAG and CVD diamond film were tested in energy range of 96 500 eV.The results showed that luminescence of Ce:YAG was obviously greater than that of CVD diamond in the energy range.Ce:YAG has been used as a proper material of fluorescence screen for soft X-rays in the XIL beamline at SSRF,with perfect pictures of diffraction patterns of the coherent X-rays. |
