IEEE Trans Appl Supercond
. 2023 Dec;
33(5).
PMID: 38046815
The metal tape co-winding or a metal-as-insulation (MI) winding method is an excellent way to improve the mechanical properties and reduce the average current density, thereby decreasing the stress in...

Park D, Dong F, Lee W, Bascunan J, Iwasa Y
IEEE Trans Appl Supercond
. 2023 Oct;
33(5).
PMID: 37789845
As a preliminary work, we have completed a 12.5-mm-cold-bore high-temperature superconducting (HTS) REBCO magnet prototype and successfully operated it up to 25 T at 10 K cooled by a cryocooler...

Park D, Bascunan J, Lee W, Iwasa Y
IEEE Trans Appl Supercond
. 2023 Aug;
33(5).
PMID: 37638131
We describe the conceptual design of a portable, liquid-helium-free, all-REBCO, 0.5-T/560-mm point-of-care magnetic resonance imaging (MRI) magnet. It is free from an external power supply and a refrigeration system during...

Natl Sci Rev
. 2023 Apr;
10(3):nwad001.
PMID: 37007748
The development of modern science and technology requires high magnetic fields exceeding 25T. Second-generation high-temperature superconducting wires, i.e. REBCO (REBaCuO-x, RE refers to Y, Gd, Dy, Eu and other rare-earth...

Dong F, Park D, Kim J, Bascunan J, Iwasa Y
IEEE Trans Appl Supercond
. 2023 Feb;
33(5).
PMID: 36816464
It is generally agreed that no-insulation (NI) high-temperature superconducting (HTS) magnets do not quench because of the turn-to-turn energy-releasing bypass unique to NI. However, these magnets, especially with high operating...
