The CMS experiment/collaboration
The CMS detector is built around a huge solenoid magnet. This takes the form of a cylindrical coil of superconducting cable that generates a magnetic field of 4 teslas, about 100 000 times that of the Earth.
The magnetic field is confined by a steel 'yoke' that forms the bulk of the detector's weight of 12 500 tonnes.
An unusual feature of the CMS detector is that instead of being built in-situ underground, like the other giant detectors of the LHC experiments, it was constructed on the surface, before being lowered underground in 15 sections and reassembled.
CMS is a collaboration of about 2000 members from about 160 institutions from all over the world, which will study pp collisions at about 10-14 TeV at the Large Hadron Collider at CERN The events produced will enabled a vast physics program including: the hunt for the Higgs boson and the search for Supersymmetry, along with the precise measurement of the top quark properties and of important Standard Model parameters.
