Future upgrades of machines like the LHC at CERN require pushing accelerator magnets beyond 10 T. Larger magnet sizes and more performing superconductors introduce additional challenges. This work improves existing analytical models of the magnetic field and stress of dipole and quadrupole sector windings, addressing how far the engineering of High Field Magnets can be pushed.
Problems and limitations of Nb3Sn magnets are identified by correlating the field intensity and the loss of field quality to the magnetic and mechanical properties of the material.been reproduced by means of an elastoplastic finite element model.
