In recent years Silicon Photomultipliers (SiPMs) have been proposed as a new type of readout system for scintillating detectors in many experiments. SiPMs consist of a matrix of parallel-connected silicon micro-pixels, which are independent photon counters working in limited Geiger mode with very high gain (~106). This contribution presents the use of an array of SiPMs (manufactured by FBK-irst) for the readout of a shashlik calorimeter composed by lead and scintillator tiles for a total of ~23 X0; the scintillator light is carried out by 64 WLS fibers (4 fibers per SiPM). The performances of the calorimeter in terms of linearity and energy resolution have been tested in a beam test with charged particles (e±, muons and pions) with a momentum up to 6 GeV/c at the CERN PS T10 line.

Abstract

In recent years Silicon Photomultipliers (SiPMs) have been proposed as a new type of readout system for scintillating detectors in many experiments. SiPMs consist of a matrix of parallel-connected silicon micro-pixels, which are independent photon counters working in limited Geiger mode with very high gain (~106). This contribution presents the use of an array of SiPMs (manufactured by FBK-irst) for the readout of a shashlik calorimeter composed by lead and scintillator tiles for a total of ~23 X0; the scintillator light is carried out by 64 WLS fibers (4 fibers per SiPM). The performances of the calorimeter in terms of linearity and energy resolution have been tested in a beam test with charged particles (e±, muons and pions) with a momentum up to 6 GeV/c at the CERN PS T10 line.
