This paper describes an optimal design method for superconducting magnets would with high temperature superconducting (HTS) tapes (e.g. Bi2223/Ag tapes). Recently, the properties of HTS tapes have been in advance and HTS magnets have been constructed and demonstrated [1]-[4]. However, the HTS tapes have thermal different characteristics compared with the low temperature superconducting (LTS) wires. Therefore it is necessary to consider these characteristics of HTS tapes at magnet design stage. We propose a new configuration of the superconducting magnets using Bi2223/Ag tapes. And the proposed configuration is optimized by using the 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 12-tesla superconducting magnet using Bi2223/Ag tape are shown.
