In many physics experiments where calorimeters are employed, the requirement of an accurate energy measurement is accompanied by the requirement of a very high hadron electron discrimination power. Normally the latter requirement is achieved by designing a high granularity detector with sufficient depth so that the showers can fully develop. This method has many drawbacks ranging from the...

The MEG searches for the undiscovered μ → e γ and aims at a better sensitivity by two orders of magnitude than the current experimental upper limit. This sensitivity enables to reach the region predicted by some models of new physics such as supersymmetric grand unified theory. For the precise measurement of the γ-ray from the μ → e γ decay, a liquid xenon scintillation detector with...

In recent years many devices have been proposed as an alternative to the photomultipliers tubes (PMTs) for the readout of scintillating detectors. Silicon Photomultipliers (SiPMs) are silicon devices composed by a matrix of pixels joined together in a common silicon substrate. Each pixel can be considered as a diode reverse biased above the breakdown voltage working in Geiger discharge mode:...
