A Method to Reveal ~(137)Cs Gamma Spectrum by a Multi-Pixel Photon Counter

摘要

An MPPC (multi-pixel photon counter) module which is composed of silicon photomultipliers (Si-PM) can be used for the photon detection and measurement. However, gamma energy spectrum could not be obtained when the module was only used. Therefore, the study was focused on finding out gamma energy spectrum of ~(137)Cs and developed a spectrometer which consisted of a MPPC module. The photopeak of 662 keV of the isotope could be revealed using the introduced method here. The used method was successful to enhance the energy resolution as well.
