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.
