✦ Synopsis
A quench in modern multifilament conductors with voltag~current characteristics, broadened due to a longitudinal inhomogeneity of a critical current, occurs at electric fields high enough to be easily registered. It provides an opportunity to control superconducting solenoids made of such conductors, even in the case when steady-state stabilization is absent.
Use of a semiempirical relationship for voltage~current cheracteristics of multifilament wires permits the computation of the main characteristics of a combined conductor consisting of such wires and of a stabilizing substrate. Presence of a thermal resistance across the boundary between the wire and the substrate decreases the quench current insignificantly, but causes a considerable drop in the electric field at which the quench OCCUrs.
