AbstraktAbstract
In this study, we present the gamma-ray detection performance of LYSO, YSO(Ce) and BGO scintillators read out by a 9 ch. micropixel avalanche photodiode (MAPD) array with a high pixel density (PD) and photon detection efficiency (PDE). The array with an active area of 11.5 x 11.5 mm(2) was assembled using single MAPDs with an active area of 3.7 x 3.7 mm(2). It had a single output signal and was developed for gamma spectroscopy. Breakdown voltage measurements were carried out for each channel, as a result of which the optimal operating voltage for the array was found. The linearity range and energy resolution for each crystal were determined in the energy range from 30 to 1770 keV. The high pixel density of the array allowed to achieve good linearity in the studied energy range.
