Abstract
This paper describes an optimal design method for superconducting magnets wound with high temperature superconducting (HTS) tapes (e.g. Bi2223/Ag tapes). The properties of HTS tapes have been advancing and HTS magnets have been constructed and demonstrated. However, the HTS tapes have thermally different characteristics compared with the low temperature superconducting (LTS) wires. Therefore it is necessary to consider these characteristics of HTS tapes at the magnet design stage. We propose a new configuration of the superconducting magnets using Bi2223/Ag tapes. The proposed configuration is optimized by using simulated annealing (SA), which is one of the optimization algorithms, under a lot of constraints such as B-I characteristic, central magnetic field, field homogeneity and so on. The details of the optimization method and an example of its application to a 12-Tesla superconducting magnet using Bi2223/Ag tape are shown.
