Numerical Analysis of the Operation Parameters of Fast Cycling Superconducting Magnets

The 100 Tm heavy ion synchrotron SIS 100 is the core component of the Facility of Antiproton and Ion Research (FAIR). Prototype magnets were built last year with the first full scale dipole magnet completed and tested. Thorough R&D resulted in FEM models which allow calculating the magnetic field of the magnet during static and dynamic mode. We illustrate the R&D steps required for the FEM calculation. We illustrate its accuracy and describe the expected field quality and dissipated power.
