English abstract:
In order to achieve the extremely high magnetic fields (8 to 10 Tesla) required for CERN's LHC (large hadron collider) project superconducting coils are used in the deflecting magnets. One possible technology is the use of the brittle material Nb,Sn, which must be kept at low temperatures (4.2 K). The cooling down process and the variation of the strong electromagnetic forces during operation require special care. These situations are simulated by a finite element model taking into account the frictional contact between the individual components of the magnet assembly. In addition to the stress and strain distribution in the magnet the knowledge of local relative motions generating frictional heat is important for the consideration of the stability of the superconducting material.
