โœฆ Synopsis

This paper reports on the simulation of winding friction likely to arise in large superconducting magnetic systems. Sample materials were the superconducting composites Cu-Nb (prepared in situ), Cu-NbTi and bronze-Nb3Sn. Instabilities of the superconducting state during essentially unstable low temperature external friction were indicated by development of normal zones in the composites. Their dependence on the frictional force jump magnitude and character is studied, and a concept of their development is proposed.

This paper presents the results of modelling the elementary mechanical effects which can be detected in epoxy-impregnated superconducting magnets. The study was carried out at 4.2 K and consisted of using three different schemes to load samples made up of a short piece of superconducting composite (
