Abstract

Scintillation crystals Gd
Al
Ga
O
 (GAGG) are considered for the application in ionizing-radiation detectors because of their high radiation resistance, density and light yield. These crystals can be used in addition to lead tungstate (PbWO
 or PWO) crystals for the development of a new generation electromagnetic calorimeter with good spatial and energy resolutions in a broad energy range. PWO crystals enable an accurate detection of high energy photons, while the addition of GAGG crystals makes it possible to precisely measure photon energies down to a few MeV units. Different options of composite electromagnetic calorimeter based on PWO and GAGG crystals are considered to optimize spatial and energy resolutions in a broad energy range (from 1 MeV to 100 GeV). The optimization is based on Geant4 simulations taking into account light collection as well as using different photodetectors and noise of electronics. The simulations are verified with the help of light yield measurements of GAGG samples obtained using radioactive sources and test beam measurements of PWO based photon spectrometer of the ALICE experiment at CERN.
