A Decay of supercurrents connected to non-superconducting zones?

Click For Summary
The discussion revolves around the effects of connecting a superconducting (SC) aluminum ring to a non-superconducting (non-SC) aluminum wire, particularly in conditions where the non-SC zone exceeds critical temperature (T > Tc). It raises the question of whether the persistent supercurrent in the SC ring will be suppressed due to the dissipation of electron pairs in the non-SC region. The complexity of the issue is highlighted, noting that many physicists struggle to provide a definitive answer and that there are currently no experiments addressing this specific scenario. The conversation emphasizes the need for further experimental investigation to understand the interactions between supercurrents and non-superconducting zones. The topic remains open for exploration, particularly in the context of the proposed experimental setup.

TL;DR
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

Thread 'Stability of persistent currents in superconductors regardless of temperature'

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
