摘要： A superconductive device (e.g., magnet) having a superconductive lead assembly and cooled by a cryocooler coldhead having first and second stages. A first ceramic superconductive lead has a first end thermally connected to the first stage and a second end thermally connected to the second stage. A jacket of open cell material (e.g., polystyrene foam) is in surrounding compressive contact with the first ceramic superconductive lead, and a rigid, nonporous support tube surrounds the jacket. This protects the first ceramic superconductive lead against shock and vibration while in the device. The rigid support tube has a first end and a second end, with the second end thermally connected to the second stage.

摘要： Apparatus for winding an electrical conductor, having a compressible electrical insulation, on a coil form to make a conductive coil. A rotating device rotates the coil form. A guiding device guides the conductor, near the coil form, longitudinally toward the second end of the coil form so that successive turns of the conductor are generally abutting and are laid down in a first layer. A locating and longitudinally-translating device moves a rotatable wheel so that its rim contacts, and is rotated by, the rotating coil form and so that a side of the wheel applies a first longitudinally-compressive force to a portion of a presently-wound turn of the first layer of the conductor in a direction toward the first end of the coil form.

摘要： An imaging apparatus, such as an MRI system, contains at least one layer of soft magnetic material between the yoke and each permanent magnet. This imaging apparatus may be operated without pole pieces due to the presence of the soft magnetic material. The permanent magnets may be fabricated by magnetizing unmagnetized alloy bodies after the unmagnetized alloy bodies have been attached to the yoke.

摘要： A racetrack shaped high temperature superconducting (HTS) coil is fabricated by layer winding HTS tape under tension on a precision coil form with a binder such as pre-preg filament-ply interlayer insulation. The coil form includes a racetrack shaped bobbin, two side plates and a series of blocks that define the outside surface of the coil. The outside surface of the winding is over-wrapped with a copper foil bonded to heat exchanger tubing. The coil is baked in the coil form to cure the epoxy then released from the coil form. The resulting coil structure is a strong winding composite built to close tolerance dimensions.
