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.

Partial insulation superconducting magnet

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 MgBmonofilament, 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.

An HTS magnet having a stack of a plurality of double-pancake (DP) coils is disclosed, with each DP coil having a first superconducting coil and a second superconducting coil. The plurality of DP coils have varying widths, with DP coils with the widest widths at the top and bottom of the stack, and DP coils with the narrowest coils located substantially at a midpoint of the stack. The DP coils omit turn-to-turn insulation, or have minimal turn-to-turn insulation.
