Multiphysics Design of HTS Magnets
Development of analysis methods that account for screening-current effects and predict magnetic-field quality, stress, strain, and operating stability in high-field REBCO magnets.
Timing Qu
Tenured Professor, Institute of Modern Physics, Fudan University
Timing Qu is a tenured professor at the Institute of Modern Physics, Fudan University. His research focuses on high-temperature superconducting (HTS) magnet technology and applications, with particular emphasis on REBCO conductors, coils, and magnet systems for fusion energy, high-field accelerator magnets, nuclear magnetic resonance, and electric power applications.
His work has established multiphysics design methods for HTS magnets that account for screening-current effects, developed multiscale characterization and damage-analysis approaches for REBCO tapes and coils, and advanced stress-control strategies for high-field HTS magnets. These studies have supported the development of 32.4 T and 35.1 T all-superconducting magnets.
