Abstract
A cryogenic system includes a superconducting magnet () in a reservoir of liquid helium (LH). Helium vapor (VH) rises and contacts a recondenser surface (″) on which the helium vapor (VH) condenses into liquid helium and flows by gravity off a lower edge of the recondenser surface. A plurality of fins () extend from the recondenser surface or a plurality of grooves (″) are cut into the recondenser surface to disrupt the film thickness and to provide a path by which droplets of the liquid helium leave the recondenser surface without travelling a full vertical length of the recondenser ().
