The CALICE Tile Hadron Calorimeter Prototype With SiPM Readout: Design, Construction and First Test Beam Results / Wattimena, N (DESY) /CALICE Collaboration
The CALICE collaboration has constructed a test beam hadronic calorimeter (HCAL) with 7608 scintillator tiles, individually read out by novel multi-pixel Geiger mode photodiodes, so called SiPMs, and tested it in electron and hadron beams at CERN. This prototype is the first device which uses SiPMs on a large scale; its purpose is to establish the technology and to record hadron shower data with unprecedented granularity for the validation of simulation models and the development of clustering algorithms..
