摘要： A solid state cooler device is disclosed that includes a first superconductor shunt, a first normal metal pad disposed on the first superconductor shunt, and a first insulator layer and a second insulator layer disposed on the normal metal pad and separated from one another by a gap. The solid state cooler device also includes a first superconductor pad disposed on the first insulator layer and a second superconductor pad disposed on the second insulator layer, a first conductive pad coupled to the first superconductor pad, and a second conductive pad coupled to the second superconductor pad. Hot electrons are removed from the first normal metal pad when a bias voltage is applied between the first conductive pad and the second conductive pad, wherein the first superconductor shunt facilitates even current distribution through the device.

摘要： Superconducting cables employ one or more superconducting tapes wound around a former. A compact superconducting cable is configured using a former having a small diameter, e.g., less than 10 millimeters. A flexible superconducting cable is configured with a former made of a flexible material. Superconducting tape conductors are wound around the former, with the superconducting layer in compression on the inside of the wind turns of the wind, to prevent irreversible damage to the superconductor. A layer of solder is on the superconducting tape(s) or solder sheaths are wound between tape conductors in each layer. The one or more solder layers or sheaths are melted to cause the solder to flow within the structure, to bond some or all of the superconducting tape conductors together and form a mechanically strong cable with an enhanced level of electrical connectivity between tapes in the cable.

摘要： This invention relates to a magnetic memory including a first superconductor wire, a second superconductor wire disposed in such a manner as to cross the first superconductor wire substantially orthogonally, a first magnetic film disposed at the point of intersection between the first and second superconductor wires and a second magnetic film interposed between the first magnetic film and the first or second superconductor films, wherein at least one of the uniaxial magnetic anisotropy within the plane of the films and coercive force of the first and second magnetic films is mutually different. Furthermore, a superconductor film containing a large number of microscopic Josephson junctions is disposed between the first and second magnetic films or on the other side of the superconductor wire connected to the magnetic film, and a lead wire for applying a current is connected to the superconductor film.

摘要： An electrical filter includes a dielectric substrate with inner and outer coils about a first region and inner and outer coils about a second region, a portion of cladding removed from wires that form the coils and coupled to electrically conductive traces on the dielectric substrate via a solder joint in a switching region. An apparatus to thermally couple a superconductive device to a metal carrier with a through-hole includes a first clamp and a vacuum pump. A composite magnetic shield for use at superconductive temperatures includes an inner layer with magnetic permeability of at least 50,000; and an outer layer with magnetic saturation field greater than 1.2 T, separated from the inner layer by an intermediate layer of dielectric. An apparatus to dissipate heat from a superconducting processor includes a metal carrier with a recess, a post that extends upwards from a base of the recess and a layer of adhesive on top of the post. Various cryogenic refrigeration systems are described.
