Characterization of a YAG:Ce calorimeter with high-energy proton beam

A YAG:Ce calorimeter with a 6×6 cm2 active area, long 10 cm has been manufactured in order to stop up to 200 MeV protons and to sustain 1MHz particle rate. It consists of four optically separated crystals assembled in the same housing. The YAG:Ce scintillator is promising for charged particle detection applications where high-count rate, good energy resolution and compact photodiode readout, not influenced by magnetic fields, are of importance. The YAG:Ce calorimeter has been characterized with proton beams up to 175MeV a The Svedberg Laboratory (TSL), Uppsala Sweden. Results obtained are shown and discussed.
