Abstract

This paper reports the optimization procedure for a no-insulation (NI) multi-width (MW) REBCO magnet, which enables the fabrication of a highly compact and competitively priced superconducting magnet. In order to identify the design considerations for the NI-MW magnet, the electromagnetic performances of 3 different magnets were investigated using the finite element method (FEM). Based on the comparison results, it was verified that the critical current distribution-factor (CCD-factor), which is the ratio of the highest pancake critical current (I<inf>c</inf>) to the lowest pancake I<inf>c</inf> within the magnet, should be close to 1.00 for the MW configuration to be most effective. In the optimized MW magnet, the center B<inf>z</inf> (7.54 T) remarkably exhibited an ∼ 51% increase compared to the 4-mm single width magnet (5.00 T). Furthermore, the CCD-factor of the optimized MW magnet was 1.04, which is quite close to 1.00, sufficiently demonstrating the validity of the optimization process and result.
