Abstract

When there is an air gap between the pancake windings in an HTS superconducting magnet, the central magnetic field is increased. To prove the effectiveness of the air gap for increasing the central magnetic field, an HTS magnet with an outsert and an insert magnet was manufactured and tested. The test results proved that the air gap between the pancake windings of the outsert magnet increased the central magnetic field by 11.0%. The critical current of the outsert magnet with the air gap increased by 73.9%. The uniformity of the magnetic field near the center of the magnet also increased. The measured values were compared with the calculated values.
