Summary

Remote delivery tubes (RDTs) in Collins and similar types of helium liquefiers interconnect the liquefier with the storage dewar. In these liquefiers the Joule-Thompson (J-T) valve is separately situated in the liquefier cryostat. The note describes the design, fabrication, and testing of a RDT with an integral J-T valve. The testing of the RDT with integral J-T showed substantial reduction in cool down time for the liquefier as well as better control of the dewar pressures.
