The Scintillator Tile Hadronic Calorimeter Prototype

A high granularity scintillator hadronic calorimeter prototype is described. The calorimeter is based on a novel photodetector – Silicon Photo-Multiplier (SiPM). The main parameters of SiPM are discussed as well as readout cell construction and optimization. The experience with a small prototype production and testing is described. A new 8 k channel prototype is being manufactured now.
