【Abstract】 Self calibration experiment of silicon photodiodes in the soft X ray spectral region of synchrotron radiation (50—2000eV) is carried out. Because of elimination of “dead region” and adoption of very thin SiO 2 layer as window of the silicon photodiode, a simple model can be used to analyze the process. Based on parameters measured by experiment, the quantum efficiency of the silicon photodiode is calculated, and the flux of incident synchrotron radiation is also obtained.更多还原
