Gamma ray detection performance of newly developed MAPD-3NM-II photosensor with LaBr3(Ce) crystal
Abstract This paper presents the gamma-ray detection performance of the newly developed MAPD-3NM-II type SiPM sensor array (4 $$\times$$ × 4) with $$\hbox {LaBr}_3$$ LaBr 3 (Ce) scintillator. The gamma-ray spectra of various sources have been measured in the energy range from 26 keV up to 1332 keV....

| Summary: | Abstract This paper presents the gamma-ray detection performance of the newly developed MAPD-3NM-II type SiPM sensor array (4 $$\times$$ × 4) with $$\hbox {LaBr}_3$$ LaBr 3 (Ce) scintillator. The gamma-ray spectra of various sources have been measured in the energy range from 26 keV up to 1332 keV. The newly developed array based on MAPD-3NM-II sensors proved $$\sim$$ ∼ 22% enhancement in energy resolution in comparison to the former MAPD-3NM-I based array. The energy resolution of 662 keV gamma-rays measured by MAPD-3NM-II was 3.3% while clearly surpassing 4.25% resolution of MAPD-3NM-I predecessor. The enhancement is related to the high PDE of the new MAPD-3NM-II. Obtained results show that the new MAPD-3NM-II demonstrated good energy resolution and linearity in the studied energy region. The energy resolution of the new detector developed based on MAPD-3NM-II was better than all previous products of MAPD. |
