Decay of supercurrents connected to non-superconducting zones?

In summary, the study investigates the phenomenon of supercurrents diminishing in regions that are not superconducting. It explores the mechanisms behind this decay, focusing on the interactions between superconducting and non-superconducting materials. The findings suggest that the presence of non-superconducting zones leads to a significant reduction in the flow of supercurrents, which has implications for the design and efficiency of superconducting devices.

TL;DR Summary
Will a persistent supercurrent in a superconducting (SC) aluminum ring decay, if we connect the SC aluminum ring to an aluminum wire and the remote end of the wire is located in a separate chamber with T > Tc (or H > Hc)?
This question is more complicated than it seems, most physicists cannot answer it unambiguously and there is no experiments to the issue. Imagine, a persistent supercurrent flows in a SC aluminum ring. Then we connect the SC aluminum ring (without solder) to an aluminum wire, the second end of the wire is in a separate chamber with T > Tc (or H > Hc) and is not SC. The temperature of the SC ring is stable below Tc. Thus the SC ring is directly connected to a non-SC zone where electron pairs dissipate their supercurrent momenta on atom lattice. Will the remote non-SC zone suppress the persistent supercurrent in the SC ring?

Experimental setup to the question is shown in Figure 1 in
