Abstract: Between a SQUID array having contact pads and a gradiometer array there is a multiplicity of superconducting connections. The superconducting connections contain a contact comb which comprises flat, substantially U-shaped, at least partially superconducting spring contacts which are electrically insulated from each other and combined with their flat sides parallel to each other and perpendicularly to the surface of the contact pads to form a packet. One leg of the spring contacts is provided with a projection which is intended as a pressure contact for one of the contact pads of the SQUID array and a further leg is associated with a pressure plate, the force of which is directed parallel to the flat side of the spring contact and perpendicularly to the surface of the contact pads. An adjusting block permits a simple adjustment of the projections on the contact pads of the SQUID array via a projection of a middle leg of the spring contact.

Abstract: A method for insulating superconductors in a magnet winding, in which any sizing and/or binders containing organic substances deposited on heat-resistant insulation used in the winding is first completely removed prior to an in-situ anneal, and at least a portion of the insulation is then provided with a special protective material. The magnet winding is then built up. The protective material is removed from the magnet winding, prior to the anneal, leaving no residue. In this way, formation of graphite from organic substances and consequent impairment of the insulation is avoided.

Abstract: A method for impregnating a superconducting magnet winding in which an annular cavity, which serves as a manifold for an impregnating medium, is left free at each end face of the winding confined by a coil form so that no molds are required, and the cost for finishing operations is minimal.
