Research on Pretension Bending of Layer Coil for 15 T DC Magnet

The 15 T DC magnet is one of the key components of the Super-X testing facility. It is composed of layer coils and pancake coils. The insulated conductor is wound into a layer coil by a pretension bending process. The plastic deformation simulation and the winding experiment for the layer coil are conducted. The key process parameters are obtained by comparing the results of the plastic deformation simulation and the winding experiment. The conductor insulation and coil dimension meet the technical requirements, and the feasibility of the pretension bending process has been verified. This article mainly introduces the research on pretension bending for layer coil of 15 T DC magnet.
