Performance evaluation of the Chinese JOINBON SiPM for radiation detection systems

JOINBON Ltd. recently released in the market a novel Silicon Photomultiplier (SiPM). In this paper we perform for the first time to our knowledge the characterization of these sensors and we verify their possible application to radiation detectors. When reading out the scintillation light of LySO crystals, we measured an energy resolution of 40% and 11% in response to respectively 65 keV and 511 keV γ-rays. The novel SiPM is obtained at a CMOS technology node and is thus compatible with the development of integrated electronics on chip.
