Review of progress and challenges of key mechanical issues in high-field superconducting magnets. [PDF]

Natl Sci Rev, 2023
The development of modern science and technology requires high magnetic fields exceeding 25T. Second-generation high-temperature superconducting wires, i.e. REBCO (REBa2Cu3O7-x, RE refers to Y, Gd, Dy, Eu and other rare-earth elements) coated conductors (

Superconducting Accelerator Magnets Based on High-Temperature Superconducting Bi-2212 Round Wires

Instruments, 2020
Superconducting magnets are an invaluable tool for scientific discovery, energy research, and medical diagnosis. To date, virtually all superconducting magnets have been made from two Nb-based low-temperature superconductors (Nb-Ti with a superconducting

An on-board 2G HTS magnets system with cooling-power-free and persistent-current operation for ultrahigh speed superconducting maglevs

Scientific Reports, 2019
Introduction of superconductor to magnetic levitation (maglev) trains greatly enhances the performances compared to those of normal conductor maglevs, e.g. from 430 km/h of the Transrapid (in Shanghai) to 603 km/h of the L0 Series in Japan.

Effect of coupling currents on the dynamic inductance during fast transient in superconducting magnets

Physical Review Special Topics. Accelerators and Beams, 2015
We present electromagnetic models aiming to calculate the variation of the inductance in a magnet due to dynamic effects such as the variation of magnetization or the coupling with eddy currents.

Alternating-gradient canted cosine theta superconducting magnets for future compact proton gantries

Physical Review Special Topics. Accelerators and Beams, 2015
We present a design of superconducting magnets, optimized for application in a gantry for proton therapy. We have introduced a new magnet design concept, called an alternating-gradient canted cosine theta (AG-CCT) concept, which is compatible with an ...

Testing beam-induced quench levels of LHC superconducting magnets [PDF]

Physical Review Special Topics. Accelerators and Beams, 2015
In the years 2009–2013 the Large Hadron Collider (LHC) has been operated with the top beam energies of 3.5 and 4 TeV per proton (from 2012) instead of the nominal 7 TeV. The currents in the superconducting magnets were reduced accordingly.
