Abstract
Abstract This invention relates to a superconducting R.F. radiation shield and method of constructing said shield. The shield structure is fabricated by wrapping a superconducting ribbon around a cylindrical form with an approximately 50 percent overlap. A thin Teflon tape is employed to insulate successive turns of the ribbon. End plugs may be provided by placing a flat sheet of Teflon across each end covered by a wide sheet of superconducting foil thereby providing an improved R.F. radiation shield for enclosing a superconducting circuit.
