| Research Abstract |
A 3-T dipole magnet was designed and constructed by utilizing high temperature superconducting (HTS) wires. Since its yoke and pole are laminated, the magnet can be excited by alternating currents. In the design, The Finite Element Method was applied to analyze magnetic fields, heat conductions and electromagnetic forces. The expected performance was realized in cooling tests and critical current measurements of fabricated coils. Coils have parts with negative curvature. We got an important knowledge to apply HTS magnets to compact gantries.
