Abstract:
IHEP (Institute of High Energy Physics, Chinese Academy of Sciences) is pursuing the R&D on advanced superconducting magnet technology for the next-generation particle accelerators, together with relevant laboratories and industries. Significant progress has been achieved in the past years: the domestic twin-aperture dipole magnet reached 12.47 T at 4.2 K in 2021; a 16 T model dipole is being fabricated and will be tested in 2023; strong collaboration for the advanced superconductor R&D (IBS & ReBCO & Nb3Sn) to significantly raise their performance and lower their costs, IBS model coil reached 60 A at 32 T; development of the CCT magnets for HL-LHC project is going well, successful design upgrade to solve the long-training problem of the previous CCT magnets. The advanced superconducting magnet technology with greatly improved performance has broad application prospects not only in the field of particle accelerators, but also in the fields of fusion energy, magnetic resonance imaging, maglev transportation and etc.
Biogrophy:
Prof. Dr. Qingjin Xu is the head of the superconducting magnet group at IHEP. After he got his PhD from the Technical Institute of Physics and Chemistry, CAS in 2006, he did his postdoc at IHEP and the High Energy Accelerator Research Organization (KEK) in Japan. He was an assistant professor at KEK from 2009 to 2014. From 2011 to 2014, he also worked at CERN as the project associate and cooperation associate. After 2014, he joined IHEP where he built the team for the high field superconducting magnet R&D, and led the development of CCT magnets for the HL-LHC project.
