(CLYC) is a new inorganic scintillator that has recently garnered attention for its ability to detect and discriminate between gammas and thermal neutrons. While scintilla tors are typically coupled to traditional photomultiplier tubes for data acquisition, this setup may not be feasible in all applications. Solid state photomultipliers offer potential advantages including smaller size, added robustness, no high voltage requirement, and imperviousness to magnetic fields. We investigate the waveform structure of CLYC emission when coupled to a SensL silicon photomultiplier and a Hamamatsu multi-pixel photon counter. We report on the ability to provide pulse-shape discrimination for gamma and thermal neutron separation.
