The Compact Muon Solenoid (CMS) is one of the experiments which are being d
esigned in the framework of the Large Hadron Collider (LHC) project at C.E.
R.N. The design field of the CMS magnet Is 4 T, the magnetic length is 12.4
8 m and the aperture is 6.36 m. This is achieved with a 4 layer-5 module su
perconducting AI-stabilized coil energised at a nominal current of 20 kA. T
he finite element analysis (FEA) carried out is axisymmetric elasto-plastic
. FEA has also been carried out on the suspension system and on the conduct
or.
