摘要：

We have assembled and tested a system of 2 detector modules containing Lutetium Fine Silicate scintillator pixels in 4 x 4 matrix, read out by multi-pixel photon counter arrays with the matching element size. The amplified signals were acquired using fast digitizers and stored for offline analysis. Using two different approaches, we have determined the single crystal relative energy resolution at 511 keV to be 14% and 12%. The coincidence time resolution has been tested using the digital constant fraction triggering and the leading edge method, and the resulting resolutions are 1.6 ns and 0.5 ns, respectively.
