THE CERN LARGE HADRON COLLIDER: ACCELERATOR AND EXPERIMENTS
The CMS experiment at the CERN LHC
CMS Collaboration
ABSTRACT: The 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 luminosi-
ties up to 1034 cm-2s-1 (1027 cm-2s-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 solid angle. Forward sampling calorimeters extend the pseudo-
rapidity coverage to high values (|| 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.
