PIN Silicon Diodes as EXAFS Signal Detectors
Journal of Synchrotron Radiation, 1996 The properties of PIN silicon diodes as X-ray detectors for EXAFS measurements with synchrotron radiation have been investigated. Electronic stability, linearity and noise current have been analyzed. The effects of diffraction peaks resulting from the crystalline nature of the diodes have been minimized by mounting the diodes on a simple device that ...
