ABSTRACT:
A method of inexpensively fabricating a superconducting cavity having thin, clean, and smooth superconductive films of excellent resonance characteristics, and the steps of forming a first thin film layer made of hydrogen transmission-preventive metal on the outer periphery of the core made of a metal having a higher ionization tendency than hydrogen in the electrochemical series, then forming a second thin film layer of superconducting material on the outer periphery of the first thin film layer, forming a third thin film layer made of a metal having a high thermal conductivity and a high bondabilty on the outside of the second thin film layer, forming a reinforced coating layer of stabilizing metal through composite fiber plated with copper on tungsten fiber on the third thin film layer, forming a cooling pipe on the outside, and then removing the core and the first thin film layer by dissolving with the surface of the superconductor being a replica of the core surface.
