Abstract

Monte Carlo simulations were carried out in order to evaluate the performance of readout solutions for monolithic LYSO blocks, considering several 2D array configurations of discrete SiPMs. Results were compared to conventional multianode PMT readout. Our findings show that a detector module based on an array of 8×8 discrete SiPM may lead to better energy resolution and comparable spatial resolution. Our work shows the feasibility of using discrete SiPMs as readout for monolithic scintillator-based detector modules.
