Abstract: A method is shown for forming a spark plug boot having at least one internal shoulder. An outer tube is first formed of an elastomeric material having an internal bore and a selected length. An inner tube, also formed of an elastomeric material, is inserted within the bore of the outer tube. The inner tube has an external diameter selected to allow it to be slideably received within the bore of the outer tube and has a length which is less than the length of the outer tube. The inner and outer tubes thus assembled are then exposed to electromagnetic radiation for a time sufficient to bond the external diameter of the inner tube to the internal bore of the outer tube.

A superconducting wire is laser welded to the bottom of the cylinder and a second niobium wire is laser welded to the top of the pin. A sleeve of a material, such as copper, aluminum, or magnesium, which at liquid helium temperatures has a much higher coefficient thermal expansion than the superconducting material, surrounds the cylinder. As a result, upon cooling the outer sleeve crimps the cylinder into a firm and uniform contact along the length of the pin.
