Abstract:
Superconducting high magnetic field technology is a key technology necessary for basic physical research. Based on domestic high-temperature superconducting (HTS) materials, the team at the Institute of High-energy Physics of the Chinese Academy of Sciences (IHEP) has broken through the core challenges of electromagnetic force control and quench protection for HTS under ultra-high current density and rapid excitation, successfully developed a superconducting prototype dipole magnet with a magnetic field of beyond 14 Tesla at 4.2 K, a new world record for dipole magnets with HTS. In parallel the team continuously pioneers next-generation high field magnet R&D with iron-based superconductors (IBS): model solenoid coil of IBS reached 49A at 35 T, the world first kA class transposed cable with IBS successfully developed, exploring the low-cost and high-performance technology for future high-energy particle accelerators.
Biography:
Qingjin Xu, leader of the superconducting magnet group at IHEP. He received his PhD from University of the Chinese Academy of Sciences in 2006. He subsequently conducted research on advanced superconducting magnet technology at the High Energy Accelerator Research Organization (KEK) in Japan and the European Organization for Nuclear Research (CERN). Since returning to China in 2014, he has led his team in the R&D of high-field superconducting magnet technology for next-generation high-energy particle accelerators, as well as its applications in areas addressing national key strategic needs.
