CALICE

The CALICE (Calorimeter for Linear Collider Experiment) collaboration is an R&D group of more than 280 physicists and engineers from around the world, working together to develop new, high performance detectors for high energy positron-electron ( e + e − {displaystyle e^{+}e^{-}} ) experiments at future International Linear Collider (ILC). It is a part of the European EUDET project. The CALICE (Calorimeter for Linear Collider Experiment) collaboration is an R&D group of more than 280 physicists and engineers from around the world, working together to develop new, high performance detectors for high energy positron-electron ( e + e − {displaystyle e^{+}e^{-}} ) experiments at future International Linear Collider (ILC). It is a part of the European EUDET project. The physics requirements of a future TeV-scale e + e − {displaystyle e^{+}e^{-}} machine, such as the ILC, demand extremely high performance calorimetry. This is best achieved using a finely segmented system that allows to reconstruct events using the so-called 'particle flow approach' (PFA). The calorimeter systems for high energy physics experiments usually consist of three main subsystems: electromagnetic calorimeter (ECAL) to detect electromagnetic showers produced by electrons (or positrons) and photons, hadronic calorimeter (HCAL) to measure hadron-induced showers, and muon tracker (or so-called tail catcher) to identify highly penetrating particles such as muons.
