“…3) modifications of the yoke lamination and the steel brackets, test of the 4KDP5 and PDP2s1 models; 4) design and manufacturing of the magnet coils with reduced end loops using the standard nuclotron wire ( filament diameter) and the new wire ( filament diameter) produced by the European Advanced Superconductor company (EAS), preparation and test of PDP2s2 and PDP3s models respectively. The results of the R&D on the 80 K yoke dipole version [8]- [10] are not discussed in this paper. Nevertheless, the reference data on the coil AC losses were obtained from those magnets tests.…”

New results from the investigation of 2 T superferric model dipoles operating at 4 T/s, 1 Hz are presented. The works are performed within the R&D program on the design of the SIS100 synchrotron at GSI in Darmstadt. One of the main research goals is minimization of overall AC power losses in the magnet at 4 K level. Different modifications of the dipole were proposed and tested experimentally. By the present time, the losses are reduced to about 17 W/m of the magnet length, while the reference Nuclotron dipole produces about 38 W/m in the same operating mode. Essential design details of the model magnets are described and further R&D steps are outlined. Index Terms-AC power losses, fast-cycling synchrotron, superconducting fast ramped dipole magnet.

The dipole magnets for the new heavy-ion synchrotron SIS-100, planned within the Facility for Anti-Proton and Ion Research (FAIR) at GSI, Darmstadt, Germany, have to be optimized under certain design requirements. At the intended high beam intensities, the field quality in the aperture is crucial. The geometry of the window-frame magnet featuring superconductive coils was already optimized with respect to the field quality in terms of higher-order multipoles using static 2D and 3D Finite Element (FE) simulations. During fast ramping up to 2 T, however, additional perturbations arise due to local saturation and due to eddy currents in both the yoke and the metallic beam pipe. These have already been investigated using transient 2D FE simulations. In order to further refine these results, a transient nonlinear 3D FE model, capturing the eddy-current effects at the end plates is used. The results are compared to those obtained by static simulations.
