innenkontakt between two coils in adjacent wicklungslagen a superconducting valve needles

摘要

The internal contact between two disc shaped or shell shaped coils in adjacent to each other arranged layers of a magnet winding of low temperature strip conductors is characterised by that the conductors (22, 23) of the coils (20, 21) having opposite winding sense surround each a core (15), are combined rigidly and are connected at their inner ends (27, 28) by means of a contact piece (30). The conductors (22, 23) of the coils (20, 21) may be supra-conductors. The contact piece (30) for coils with tie bands (32) may have notches (34) for their acceptance. The contact piece (30) may consist of normal-conductive material which may be covered at least in part by a supra-conductive layer or at least at the plane surface against which lie the two winding ends (27, 28) a foil of high current superconductive material is provided.
