calorimeter system การใช้

All particles except muons and neutrinos deposit all their energy in the calorimeter system by production of electromagnetic or hadronic showers.
This behaviour is exploited in muon spectrometers in high-energy physics experiments by installing muon detectors behind the calorimeter systems or behind thick absorber materials.
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.
Further out from the beam pipe, OPAL's calorimeter system was divided into electromagnetic calorimeters ( for the electrons identification ), hadron calorimeters ( for hadrons ) and forward calorimeters placed around, and close to, the beam pipe at the two ends of the detector to catch particles thrown forwards by collisions in LEP . Muon detectors formed the end caps of the detector.
