Patent number: 10804018Abstract: The present invention is a superconducting partial insulation magnet and a method for providing the same. The magnet includes a coil with a non-insulated superconducting wire winding wound around a bobbin. The coil has a first wire layer, a second wire layer substantially surrounding the first layer, and a first layer of insulating material disposed between the first wire layer and the second wire layer. Each wire layer comprises a plurality of turns, and the first layer of insulating material substantially insulates the second wire layer from the first wire layer.Type: GrantFiled: September 21, 2017Date of Patent: October 13, 2020Assignee: Massachusetts Institute of TechnologyInventors: Seungyong Hahn, YoungJae Kim, John Peter Voccio, Juan Bascunan, Yukikazu Iwasa

Patent number: 10580573Abstract: A superconducting magnet and method for making a superconducting magnet are presented. The superconducting magnet is made by forming a coil from windings of a first wire comprising a reacted MgB2 monofilament, filling a cavity of a stainless steel billet with a Mg+B powder. Monofilament ends of the first wire and a similar second wire are sheared at an acute angle and inserted into the billet. A copper plug configured to partially fill the billet cavity is inserted into the billet cavity. A portion of the billet adjacent to the plug and the wires is sealed with a ceramic paste.Type: GrantFiled: March 13, 2017Date of Patent: March 3, 2020Assignee: Massachusetts Institute of TechnologyInventors: Seungyong Hahn, Yukikazu Iwasa, Juan Bascunan, John Peter Voccio, Jiayin Ling, Jungbin Song, YoungJae Kim

Patent number: 10079092Abstract: High-temperature superconducting (HTS) devices and methods are disclosed. An HTS cable subassembly has a rectangular shaped cross section. The subassembly includes a stack of tapes formed of a superconducting material, and a cable subassembly wrapper wrapped around the stack of tapes. The tapes in the stack are slidably arranged in a parallel fashion. A cable assembly is formed of a cable assembly wrapper formed of a second non-superconducting material disposed around an n×m array of cable subassemblies. Within a cable assembly, a first cable subassembly of the array of subassemblies is oriented substantially perpendicular to a second cable subassembly with regard to the plurality of tapes. A compound-cable assembly is formed by joining two or more cable assemblies. A high-temperature superconducting magnet is formed of a solenoidal magnet as well as dipole and quadrupole magnets wound of a cable subassembly, a cable assembly, and/or a compound cable assembly.Type: GrantFiled: November 25, 2015Date of Patent: September 18, 2018Assignee: Massachusetts Institute of TechnologyInventors: Yukikazu Iwasa, Juan Bascuñán, Seungyong Hahn
