Testing of Series Superconducting Dipole Magnets for the SIS100 Synchrotron

The FAIR project in Europe is a new international accelerator complex which is currently under construction in Darmstadt, Germany. The high intensity primary beam for the experiments will be provided by the SIS100—a heavy ion synchrotron with magnetic rigidity of 100 Tm. The SIS100 has a circumference of 1.1 km and utilizes 415 fast cycling superconducting magnets, of which 108 are dipoles. The series production of the dipole magnets began in November 2016 and the first magnet was delivered in September 2017. Each magnet is subjected to a comprehensive testing program at both ambient and cryogenic conditions. The main parameters to be verified are the hydraulic and electrical integrity, geometrical dimensions, assembly precision, and magnetic field quality. This work presents the up-to-date status of the series dipole magnet production, the testing strategy, an overview on the selected measurement systems, and the main results enhanced with statistical data.
