Research on Tension-Free Bending of 15 T DC Magnet

The 15 T DC magnet is one of the key components of Super-X testing facility. The magnetic field configuration and uniformity depend on the shape accuracy of the background coil. There are 31 radial turns of the coil. Tension-free bending analysis for the coil turns with specific radii was carried out. The pressing distance of the pressing wheel for turns bending has been obtained. The reliability of the finite element model is verified by comparing calculated tension-free specific radii with the experimental results of a tension free bending test. It provides the technical parameters support for the tension-free bending of background coil.
