English AbstractThe compact muon solenoid (cms) detector is described. the detector operates at the large hadron collider (lhc) at cern. it was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 tev (5.5 tev nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). at the core of the cms detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. the iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. the overall dimensions of the cms detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t.
