  • Publication number: 20210384403
    Abstract: A bulk superconductor device is disclosed, comprising a single grain RE-BCO element incorporating reinforcing fibres. The single grain (RE)BCO element comprises RE-211 pinning sites disposed in a RE-123 matrix and further comprises Ag. The reinforcing fibres comprise a ceramic such as SiC and a refractory metal such as W. The reinforcing fibres comprise a core formed of the refractory metal and a ceramic cladding surrounding the core. The device may be manufactured by a top seeded melt growth process or by a top seeded infiltration growth process.

  • Patent number: 10179033
    Abstract: Present example embodiments relate generally to a surgical system comprising an internal anchor assembly configurable to be inserted into and positioned inside a cavity of a body. The surgical system further comprises an external anchor assembly configurable to magnetically couple to the internal anchor assembly. The external anchor assembly may comprise a magnetic assembly. The magnetic assembly may include one or more superconducting magnets configurable to generate a magnetic field. The magnetic assembly may further include a conductive housing for receiving the one or more superconducting magnets. The external anchor assembly may further include a temperature control section configurable to control a temperature of the one or more superconducting magnets via the conductive housing. The external anchor assembly may further include an external anchor body configurable to receive the magnetic assembly and the temperature control section.
