Abstract

The 56 mm single aperture superconducting dipole model with a 5-block coil configuration was reassembled and tested to investigate the full support of electromagnetic forces using a high-manganese steel collar structure without mechanical contribution from an iron yoke. The reassembled model, which has a gap between the high manganese steel collar and the horizontally split iron yoke, reached a central field of 9 tesla (93% of short sample) at the first quench and attained the short sample limit with a few following quenches. The test results of the training quenches and the mechanical behavior after the modification are described.
