Abstract

A process for manufacturing superconducting magnets is described. Two conducting tapes are assembled with an insulating ceramic layer deposited between facing sides of the tapes. The tapes and the insulative refractory material are bonded together by, for example, rolling to result in a self insulating substrate tape to which superconducting composition precursors are applied for later annealing. In one aspect, the composite tape is then wound to result in a pancake coil which is exposed to high temperatures in an oxidizing environment to convert the superconducting precursors to superconducting materials. The resultant high temperature superconducting composition coil can then be used as a high temperature superconducting magnet with appropriate conducting connectors applied thereto.

Dependent claims

A self insulating substrate tape, comprising:

a first conducting tape having a facing side;
a second conducting tape having a facing side facing the facing side of said first conducting tape;
an electrically insulating layer interposed between the first conducting tape and the second conducting tape, and securing said first conducting tape to said second conducting tape by adhering to the facing sides of said first conducting tape and said second conducting tape, said electrically insulating layer being capable of withstanding temperatures sufficiently high to make superconducting materials from refractory materials to be applied on the non-facing sides of the first and second conducting tapes without substantially degrading the electrically insulating properties of said layer;
and
a layer of one of a superconducting material and a superconducting material precursor on each of said first conducting and second conducting tapes on the sides thereof opposite said facing sides.
