Recent progress of HTS magnet using Bi-2223 Ag-sheathed wire

The progress on the development of high temperature superconducting magnets using Bi-2223 Ag-sheathed wire is reported. Two types of refrigerator cooled high temperature superconducting magnets, namely, a high magnetic field type and a large bore type, were successfully constructed. The magnets were developed using Bi-2223 silver-sheathed tape wire. Results show that one of the most important benefits of the magnets is their capability of rapid excitation.
