Different crystals with SiPM array readout were tested in laboratory. Hygroscopic crystals, suchas LaBr3:Ce and CeBr3, and innovative non-hygroscopic crystals, such as PrLuAg and CeCAAGwere studied. 4×4 SiPM arrays from different manufacturers were used as photodetectors.Best results were obtained with LaBr3:Ce crystals read by Hamamatsu S13361 TSV arrays. ForLaBr3:Ce crystals, due to their high photon yield, it was possible to implement a simple readoutscheme based on CAEN V1730 FADC, without any amplification. Energy resolutions (FWHM)better than 4% were obtained at the Cs137peak, with a detector linearity better than 2%.
