Verwendung eines Kontaktierdrahtes aus einer Bleilegierung in einer Supraleitervorrichtung

摘要

The contact wire comprises a Pb alloy, with Pb as the main element, the other elements including at least one within the series comprising Cu, Ga, Ge, Se, Ag, In, Sn, Sb, Te, Au, Tl, Bi, Pd and Pt, for obtaining a thin wire via a liquid quenching process.Pref. the thin alloy wire is used between a superconductor chip and an external lead or between alpha superconductor chips, with a metallised surface on one side of the chip made of an alloy of the same materials as the wire.Pref. the superconductor chip has a laminated structure with a Si layer, a Nb layer and a metallised surface layer
