Title: Laminated magnet field coil sheath

Abstract

A method for manufacturing a magnetic cable trim coil in a sheath assembly for use in a cryogenic particle accelerator. A precisely positioned pattern of trim coil turns is bonded to a flexible substrate sheath that is capable of withstanding cryogenic operating conditions. In the method of the invention the flexible substrate sheath, with the trim coil pattern precisely location relative to a bore tube assembly of an accelerator and is then bonded to the bore tube with a tape suitable for cryogenic application. The resultant assembly can be readily handled and installed within an iron magnet yoke assembly of a suitable cryogenic particle accelerator. 1 fig.

  • Electromagnetic coils of laminated, foil construction are suitable for use in guideways of magnetically-levitated-vehicle systems. The coils are each constructed by applying a double-sided adhesive tape of insulating material to both surfaces of a continuous ribbon of conductive foil to form a tri-layer laminate or matrix. Then, the tri-layer matrix is shaped into a coil of a desired configuration. The coil loops or turns are formed by folding the tri-layer matrix along diagonal fold lines in selected bend regions so as to transpose the top and bottom surfaces of the laminate on either side of the folds, and bring themore » surface interior of the folds into contact. The insulating material in the laminate is omitted from the interior bend regions, so that, after folds have been made, the interior surfaces in those regions are exposed foil which electrically contact one-another. With this construction, each turn of the coil is separated electrically from adjacent turns by two layers of insulation covering a single layer of foil, except in the bend regions, where two layers of foil are present on the interior of the folds, along with two layers of insulation along the exterior the folds. Alternative constructions in the bend regions avoid unsightly bulging in that area. 21 figs.« less
  • During manufacture of the Nb/sub 3/ Sn superconductor for the LCP the final heat treatment was found to cause a significance loss of tensile ductility and fracture toughness properties of the conductor sheath alloy at 4 K; the weld metal regions were found to be particularly susceptible. This necessitated a testing program with the purpose of selecting and qualifying an alloy which would successfully replace Nitronic 40, the original alloy, and in this paper the work of that program is presented, from a description of its procedures and acceptance criteria to a comparative analysis of the final candidates for themore » new sheath alloy: A-286, JBK-75, and Kromarc 58. Each of them satisfied the acceptance criteria. JBK-75 was selected for its greater reliability and intrinsically better weldability over A-286, and for its greater commercial availability over Kromarc 58.« less
