Compact Solenoid Muon
CMS ( Compact Muon Solenoid : compact solenoid with muons) is one of the 5 experiments of the future collider LHC. It is about a detector of particles the purpose of which will be to discover the Boson of Higgs like various supersymmetric particles . All its particles are predicted by various theories, but were never observed in experiments to date. He is added to a similar detector, Atlas, which will have the same functions appreciably. He should take up duty in 2008, at the time of the starting of LHC, at the point number 5 of the beams.
Whereas the gigantism of ATLAS forced to build it directly in the corresponding cavity along the particle accelerator, the CMS is him builds “section by section” on the surface; these sections will be descended to one in the cavity in the course of excavation, and will be assembled in a long cylinder. It will be used in particular as experiment of confirmation for the results of ATLAS.
The construction of this detector represented a real challenge. As example, the mass of data collected at the time of a collision is so enormous that it cannot be safeguarded with each collision (it will occur every 25 nanoseconds of them). It was thus necessary to invent the new shape of “release” which analyzes the first results of the collision and decides, according to their interest, to safeguard them or not before the following collision.
