Mechanical Behavior Analysis of Model Coil for the 40-T Hybrid Magnet Superconducting Outsert

摘要

A 40 T hybrid magnet system will be designed and constructed at the High Magnetic Field Laboratory, Chinese Academy of Sciences. The superconducting outsert consists of two concentric superconducting coils. After the conceptual design of the superconducting magnet, the Ru00026;D of the ${rm Nb}_{3}{rm Sn}$ model coil is now being carried out as an explorative research item. In this paper, the preliminary structural design of the model coil is introduced. For comparison, two different methods are used to analyse the mechanical behavior of the ${rm Nb}_{3}{rm Sn}$ coil during normal operation; the first is a traditional method called global-local finite element technique, the second is a detailed 2-D FEA method.
