Summary
The heavy ion accelerator SIS100 is the leading machine of the international Facility for Antiproton and Ion Research (FAIR) under construction at GSI in Darmstadt, Germany. The layout of the synchrotron is based on fast-cycling superconducting magnets of the super-ferric window-frame type. The magnets had been developed within an intensive cooperation work between JINR and GSI/FAIR for optimization of the basic Nuclotron concept and adjusting the detailed design to the requested operation parameters. The main dipoles will ramp with 4 T/s and with a repetition frequency of 1 Hz up to a maximum magnetic field of 1.9 T. The field gradient of the main quadrupole will reach 27.77 T/m. The integral magnetic field length of the horizontal/vertical steerer and of the chromaticity sextupole corrector magnets will provide 0.403/0.41 m and 0.383 m, respectively. Production and testing of the SIS100 dipoles were in the responsibility of GSI. The series production of the high current quadrupoles and of the individually ramped low current corrector magnets was started in 2020 at the JINR in Dubna. We present our experience on stable series production and effective testing procedures for reproducible cryogenic operation properties and high-resolution measurements of the magnetic field parameters.
