Journal ArticleDOI
Magnetization and screening current in an 800 MHz (18.8 T) REBCO nuclear magnetic resonance insert magnet: experimental results and numerical analysis
Yi Li,Dong Keun Park,Yufan Yan,Yoonhyuck Choi,Jiho Lee,Philip C. Michael,Siwei Chen,Timing Qu,Juan Bascunan,Yukikazu Iwasa +9 more
TL;DR: In this paper, the authors presented experimental and simulation studies on the screening current effect on an 800-MHz (18.8-T) REBCO insert (H800) that together with a 500-MHz LTS/HTS NMR magnet (L500) constitutes the MIT 1.3G component.
Journal ArticleDOI
Screening-Current-Induced Strain Gradient on REBCO Conductor: An Experimental and Analytical Study With Small Coils Wound With Monofilament and Striated Multifilament REBCO Tapes
Yi Li,Dong Keun Park,Woo Seung Lee,Yoonhyuck Choi,Hiromi Tanaka,Juan Bascunan,Yukikazu Iwasa +6 more
TL;DR: In this paper, the authors present results of an experimental and analytical study on screening-current-induced strain gradients, performed with small REBCO pancake coils, wound with monofilament and 3-striate/4-filament tape.
Journal ArticleDOI
Design Overview of the MIT 1.3-GHz LTS/HTS NMR Magnet with a New REBCO Insert
TL;DR: In this paper, the authors presented a design overview of the MIT 1.3 GHz LTS/HTS NMR magnet (1.3G) with a newly designed 835-MHz REBCO insert (H835) as a replacement for the 800-MHz RBCO Insert (H800) that was damaged when it quenched during operation in 2018.
Journal ArticleDOI
