R&D works for Superconducting Magnet for Future Accelerator Applications in Japan

Abstract

KEK cryogenics science center is developing superconducting magnet technology for future accelerator science. Three major technological categories are focused; 1) high precision 3D magnetic field technology based on the g-2/EDM magnet developments, 2) rad-hard superconducting magnet technology based on the COMET magnet developments, and 3) high magnetic field superconducting magnet technology for future colliders based on the LHC MQXA and HL-LHC D1 magnet developments. Extensive studies including Nb3Sn conductor and magnet developments for high field magnets and HTS for rad-hard superconducting magnets are ongoing with various collaboration programs such as the US-Japan research collaboration.
