Latest Patents

One of his latest patents is a vapor cooled current lead for a superconducting device located in a cryostat. This innovative design includes a normal conductor section that extends from ambient conditions inward to an intermediate point. The composite lead features a ceramic high-temperature superconductor core with a metallic sheath, which is arranged in a helical path to minimize heat leak by conduction. The metallic sheath is strategically stripped away at intervals, and the gaps are filled with a filler that provides mechanical strength and reduces thermal conduction. A flow of cryogen vapor, directed by a tubular housing, maintains the high-temperature superconducting material below its critical temperature while cooling the normal conductors.

Another notable patent involves a method of making a conductor for a high energy density hyperconducting inductive coil. This design includes a multicomponent conductor made up of several components, each consisting of a cable of conductive material twisted around a longitudinal axis. The cable is wrapped helically and compacted to minimize voids, giving the component a polygonal profile. The components are arranged parallel to one another, with mutually facing sides in contact. An electrical insulating and support structure surrounds the conductor, supporting stresses induced by magnetic fields created by the current flow.
