Query: Supercurrent in a mesoscopic proximity wire   Recent experiments on the proximity induced supercurrent in mesoscopic normal
wires revealed a surprising temperature dependence. They suggest clean-limit
behavior although the wires are strongly disordered. We demonstrate that this
unexpected scaling is actually contained in the conventional description of
diffusive superconductors and find excellent agreement with the experimental
results. In addition we propose a SQUID-like proximity structure for further
experimental investigations of the effects in question.
