Irradiation and performance of RGB-HD Silicon Photomultipliers for calorimetric applicationsJan 24 2019Silicon Photomultipliers with cell-pitch ranging from 12 $\mu$m to 20 $\mu$m were tested against neutron irradiation at moderate fluences to study their performance for calorimetric applications. The photosensors were developed by FBK employing the RGB-HD ... More
