Three-Dimensional Quench Calculations for the FAIR Super-FRS Main Dipole

The Super-FRS (superconducting fragment separator) will be constructed in the frame of the Facility for Antiproton and Ion Research project at GSI (Darmstadt, Germany). This work presents quench calculations done on the Super-FRS main dipole magnet. Two quench programs were used. One developed at CIEMAT (Madrid, Spain), and the other developed at GSI. Both quench programs use finite-difference method. For the GSI quench program the mesh size influence was investigated. A protection system for Super-FRS dipoles is presented as well. Optimum energy extraction resistors for the Super-FRS dipoles were calculated. Quench calculations are compared to measurements done on the first dipole prototype.
