摘要： A method for restoring superconductivity of a wire having a core of reacted MgB2 comprises subjecting said wire to a two-phase heat treatment, wherein a first phase comprises heating in a range of 800° C. to 1000° C. during 20 minutes to 40 minutes and a second phase comprises heating in a range of 550° C. to 750° C. during 45 minutes to 75 minutes.

摘要： Operational characteristics of an extremely low resistance (“ELR”) film comprised of an ELR material may be improved by depositing a modifying material onto appropriate surfaces of the ELR film to create a modified ELR film. In some implementations of the invention, the ELR film may be in the form of a “c-film.” In some implementations of the invention, the ELR film may be in the form of an “a-b film,” an “a-film” or a “b-film.” The modified ELR film has improved operational characteristics over the ELR film alone or without the modifying material. Such operational characteristics may include operating in an ELR state at increased temperatures, carrying additional electrical charge, operating with improved magnetic properties, operating with improved mechanic properties or other improved operational characteristics. In some implementations of the invention, the ELR material is a mixed-valence copper-oxide perovskite, such as, but not limited to YBCO. In some implementations of the invention, the modifying material is a conductive material that bonds easily to oxygen, such as, but not limited to, chromium.

摘要： The present invention addresses a problem of providing an MgB2 wire material having a small reversible bending radius, a superconducting coil using the same, and an MRI without lowering a critical current value and a critical current density of the MgB2 wire material to an extreme. To solve the problem, provided are a superconducting wire having a plurality of MgB2 strands and a first base metal, a superconducting coil using the same, and an MRI, the superconducting wire being characterized in that in a cross section orthogonal to a wire longitudinal direction, a center point of an area surrounded by the plurality of MgB2 strands and a center axis of a cross section of the superconducting wire are disposed in separated positions.

摘要： The present disclosure relates to a superconductor including magnesium diboride and a production method therefor. A superconductor having a high critical current density at a certain temperature and under a certain magnetic field may be obtained by doping magnesium diboride with liquid chloroform during the production of the superconductor.

摘要： A system and method for fabricating accelerator cavities comprises forming at least two half cavities and joining the half cavities with a longitudinal seal. The half cavities can comprise at least one of aluminum, copper, tin, and copper alloys. The half cavities can be coated with a superconductor or combination of materials configured to form a superconductor coating.
