Paper Abstract

Production of superfluid (4HeII) helium from a reservoir of supercritical helium offers an option in the cooling of instruments and the transfer of helium in a low-g environment. The problem with small Joule-Thomson Expanders (JTX) has been a tendency toward the plugging of capillary expanders. A JTX has been designed using porous plugs as expander elements to reduce the potential for plugging. Superfluid helium has been produced continuously for an hour and a half using unfiltered liquid helium.
