  $Cs_2LiYCl_6:Ce^{3+}$ (CLYC) is an inorganic scintillator that has recently
garnered attention for its ability to detect and discriminate between gammas
and thermal neutrons. We investigate several important performance parameters
of three different solid state photomultipliers (SSPMs) when reading out CLYC
crystals: linearity, energy resolution, and pulse shape and discrimination
ability. These performance parameters are assessed at a variety of temperatures
between -20$^{\circ}$C and +50$^{\circ}$C.
