Abstract
Abstract
Compared with a small magnet, the magnet for IMW HTS DC induction heater is larger, and the radius reaches up to 2200mm, which will bring great difficulties to the winding of superconducting magnets. To ensure that the design and fabrication of the large-diameter HTS DC magnet can be a one-shot success, some smaller HTS magnets, including three 200 mm diameter magnets and two 600 mm diameter magnets, have been designed and fabricated. The structure of these magnets is similar to the final 2200 mm diameter prototype magnet, which is wound in a spiral way. Performance test results of all the superconducting magnets have proved that the winding process and curing process of the magnet is feasible and can be used to make large-diameter magnets formally.
