N2 - We designed and realized the front-end readout circuit for a matrix of silicon photomultipliers (SiPM), to be used in handheld dual particle imagers. In this work, we optically coupled two 6-mm by 6-mm by 6-mm stilbene crystals to two separate pixels on the same SiPM matrix and studied the performance of the readout architecture in terms of energy resolution and timing. A Na-22 source was placed on the array between the two pixels and energy and time resolution were measured. We varied the resistance of the AC stage of the readout circuit for each pixel by placing resistors of various resistance values in parallel with the signal readout jack. The energy resolution of the system improved with increasing resistance values, as expected. The time resolution in the 200 to 400 keV energy band did not vary significantly as a function of resistance value.
