In this paper. we briefly review our recent progress on development of core technologies for 2G HTS NMR/MRI magnets at Korea University. To outperform the current state-of-art NMR/MRI magnet systems. we have developed the following technologies: 1) a REBCO-REBCO superconducting joint for operation of persistent current mode; 2) partial and grease-insulation winding techniques for self... https://www.macorners.shop/product-category/tape-measure/
