Patent number: 11688537Abstract: An electromagnet assembly has an inner magnet, an outer magnet, arranged around the inner magnet with an annular region extending between the inner magnet and the outer magnet, and a number of support elements extending through the annular region and dividing the annular region into a number of annular segments. The support elements are distributed in the annular region so as to form a small annular segment and a large annular segment.Type: GrantFiled: July 27, 2021Date of Patent: June 27, 2023Assignee: Siemens Healthcare LimitedInventors: Alun Down, Jonathan Noys

Patent number: 11101060Abstract: A high temperature superconducting, HTS, field coil. The HTS field coil comprises a plurality of turns and a partially insulating layer. The plurality of turns comprises HTS material and metallic stabilizer. The partially insulating layer separates the turns, such that current can be shared between turns via the partially insulating layer. The partially insulating layer comprises an electrically conducting layer, and first and second insulating layers. The electrically conducting layer is coated on one side with the first insulating layer and on the other side with the second insulating layer. Each insulating layer has one or more windows through which electrical contact can be made between the turns and the electrically conducting layer. The windows in the first insulating layer are offset in the plane of the electrically conducting strip from the windows in the second insulating layer.Type: GrantFiled: January 31, 2019Date of Patent: August 24, 2021Assignee: Tokamak Energy LtdInventors: Robert Slade, Marcel Kruip, Bas van Nugteren, Greg Brittles, Enrique Ruiz de Villa Valdés, Rod Bateman, Alun Down

Patent number: 10878983Abstract: An electromagnet assembly has an outer shield coil assembly having a first end and a second end, and further has a housing having a first end wall and a second end wall spaced apart from one another by a side wall. The outer shield coil assembly and housing are centered on a common assembly axis. A first support pin extends between and couples the first end wall of the housing and the first end of the outer shield coil assembly. A second support pin extends between and couples the second end wall of the housing and the second end of the outer shield coil assembly. Hence the outer shield coil assembly is carried by the housing by the pins. The coupling of the end walls of the housing and ends of the outer shield coil assembly is configured to prevent relative radial and rotational movement between the outer shield coil assembly and the housing.Type: GrantFiled: March 23, 2018Date of Patent: December 29, 2020Assignee: Siemens Healthcare LimitedInventors: William James Bickell, Jonathan Noys, Alun Down
