Two device geometries, a Josephson junction and a gate-defined quantum point contact, are used to characterize interface transparency and the two-step proximity effect. In the Josephson junction, multiple Andreev reflection reveal near-unity transparency, with an induced gap $\\Delta^*=0.50~\\mathrm{meV}$ and a critical temperature of $7.8~\\mathrm{K}$. Tunneling spectroscopy yields a hard induced gap i","authors_text":"A. C. C. Drachmann, B. Shojaei, C. J. palmstr{\\o}m, C. M. Marcus, F. Nichele, H. J. Suominen, M.
