The Compact Muon Solenoid (CMS) detector is described. operates at the Large Hadron Collider (LHC) CERN. It was conceived to study proton-proton (and lead-lead) collisions a centre-of-mass energy of 14 TeV (5.5 nucleon-nucleon) and luminosities up 1034 cm−2 s−1 (1027 s−1). At core CMS sits high-magnetic-field large-bore superconducting solenoid surrounding an all-silicon pixel strip tracker, lead-tungstate scintillating-crystals electromagnetic calorimeter, brass-scintillator sampling hadron...
CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV Large Hadron Collider (LHC). It currently involves more than 2000 physicists from 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle based on its unprecedented collision energy luminosity when it begins operation in 2007.
