Method for manufacturing a superconductive coil element
The fabrication is described of a superconductive coil element comprising a layer of superconductive material and a layer of insulating material, each alternately arranged in a helical form centered about a common axis with their adjacent turns tightly attached to each other. The superconductive coil element exhibits a maximum critical current density when an electromagnetic field acting on the surface of said superconductive layer is substantially at an angle of 90/sup 0/. The method of manufacture comprises relatively disposing the substrate and evaporation sources which respectively consists of the superconductive material and insulating material with the adjacent planes of the substrate and evaporation sources facing each other, interposing a perforated shield between the substrate and the sources, rotating the substrate and evaporation sources relative to each other and evaporating the superconductive material and insulating material at the same time separately from each other to successively deposit same on an annular region of the substrate.
