✦ Synopsis

The value of critical current (I c ) in high temperature superconductor (HTS) tape has a great in¯uence on vertical ®eld (Bc). Therefore, in the shape design of HTS magnet, a method to reduce the Bc should be considered in order to maintain the stability and substantial improvement on the performance. This paper presents the advanced racetrack HTS magnet which is used as ®eld coil in the high temperature superconducting generator (HTSG) and the results of the approach are compared with I c of the initial design magnet. On the basis of the magnetic ®eld analysis using Biot±Savart's law and 2-dimensional ®nite element analysis (2D FEA), this study is focused on the function of iron plates, which is to obtain smaller Bc, and they are applied to both initial and optimized magnets. Moreover, the design approach is veri®ed by comparison with those experimental results.
