Quench Calculations and Measurements on the FAIR Super-FRS Dipole.

Abstract: The FAIR project undertaken at GSI (Darmstadt, Germany) will lead to the construction of 2 superconducting synchrotrons and one superconducting fragment separator called Super-FRS. This paper presents quench measurements and calculations on the FAIR Super-FRS dipole using two different 3D FEM programs. The first (called Opera Quench) gives the same order of propagation velocities as those computed with a 1D program. The second (developed by CIEMAT) succeeds to reproduce the current drop and quench resistance measured on the Super-FRS dipole. [Copyright &y& Elsevier]
