Effective longitudinal segmentation of shashlik calorimeters can be achieved taking advantage of the compactness and reliability of SiPMs. These photosensors can be embedded in the bulk of the calorimeter and are employed to design very compact shashlik modules that sample electromagnetic and hadronic showers every few radiation lengths. In this paper we discuss the performance of a calorimeter made up of twelve such modules and able to sample showers every ~ 4X0. In summer 2016, this prototype has been exposed to electrons, muons and hadrons at CERN-PS (East Area T9 beamline). The performances in terms of energy resolution, linearity, response to minimum ionizing particles and reconstruction of the shower profile are discussed.

Abstract
Effective longitudinal segmentation of shashlik calorimeters can be achieved taking advantage of the compactness and reliability of SiPMs. These photosensors can be embedded in the bulk of the calorimeter and are employed to design very compact shashlik modules that sample electromagnetic and hadronic showers every few radiation lengths. In this paper we discuss the performance of a calorimeter made up of twelve such modules and able to sample showers every ~ 4X0. In summer 2016, this prototype has been exposed to electrons, muons and hadrons at CERN-PS (East Area T9 beamline). The performances in terms of energy resolution, linearity, response to minimum ionizing particles and reconstruction of the shower profile are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
