Abstract: A superconductor (10, 30) has a twisted structure and is adapted to form windings in a superconducting coil. The superconductor (10, 30) comprises at least one superconductor wire. The superconductor further comprises at least one elongated electrical insulation element (18, 37). The elongated electrical insulation element(s) (18, 37) is/are twisted with or around the superconductor wire(s) in order to create a separation distance with an adjacent superconductor wire in a neighbouring winding, The elongated electrical insulation element(s) (18, 37) and the superconductor wire(s) may be twisted in one and the same twisting operation.

Abstract: A magnesiumdiboride (MgB2) powder-in-tube (PIT) wire has a cross-section showing —voids, —magnesiumdiboride, and —oxides, as measured by energy-dispersive X-ray spectroscopy. Oxides are located at the borders between the voids and the magnesiumdiboride. The MgB2 PIT wire has a higher degree of superconductivity.

Abstract: There is provided a method of manufacturing a continuous wire comprising forming a strip formed from at least one metallic material into a channel, placing at least one powder into the channel and sealing edges of the channel together to produce a wire, wherein the method further comprises mixing the powder with a carrier liquid to create a slurry and placing the slurry into the channel. The carrier liquid is chemically inert with respect to the at least one powder.
