    摘要: A superconductive lead assembly for a superconductive device (e.g., magnet) cooled by a cryocooler coldhead having first and second stages. A first ceramic superconductive lead has a first end flexibly, dielectrically, and thermally connected to the first stage and a second end flexibly, dielectrically, and thermally connected to the second stage. A first glass-reinforced-epoxy lead overwrap is in general surrounding contact with and attached to the first superconductive lead. The first lead overwrap has a coefficient of thermal expansion generally equal to that of the first superconductive lead. The lead overwrap protects the lead from moisture damage and from breakage during handling. For added protection against shock and vibration while in the device, the lead assembly is surrounded by a (e.g., polystyrene foam) jacket surrounded by a helically-wound metallic wire surrounded by a glass-reinforced-epoxy jacket overwrap surrounded by a rigid support tube.

    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: A superconductive magnet has a superconductive coil surrounded by a thermal shield surrounded by a vacuum enclosure. The thermal shield has one and preferably several flexible layers of thermally conductive material. A first flexible blanket of multi-layer thermal insulation surrounds the thermal shield within the vacuum enclosure, and a second such flexible blanket surrounds the superconductive coil within the thermal shield. A cryocooler coldhead has a first stage in thermal contact with each of the flexible layers of the thermal shield. At least most of the weight of the thermal shield is supported by the flexible blankets.

    摘要: An embedded eddy current inspection apparatus includes a substrate having an opening, and a test eddy current coil (“test coil”) affixed to the substrate near the opening. An internally inspected multilayer component structure includes an upper layer, a lower layer, and an eddy current probe embedded between the upper and lower layers. The eddy current probe includes the test coil facing a subject layer selected from the upper and lower layers. A method of inspecting a multilayer component structure includes simultaneously energizing the test coil and a reference eddy current coil (“reference coil”) embedded between the upper and lower layers and facing the subject layer. The reference coil is located in a reference region of the multilayer structure. A test signal from the test coil is compared with a reference signal from the reference coil, to determine whether a flaw is present in the subject layer near the test coil.
