Highlights What are the main findings? 1. A light readout from scintillators by means of a SiPM can or cannot give rise to non-linearity at a high energy, depending on the light decay time and on the number of SiPM microcells.What is the implication of the main finding? 1. A careful choice of scintillator and SiPM can…
