✦ Synopsis

A ZHe/"He dilution refrigerator is described where a commercial two-stage Gifford-McMahon refrigerator (Leybold RGD 210) cools the dilution unit and the radiation shields of the cryostat. This work is a continuation of previously described experiments where a more powerful closed cycle refrigerator had been used for the same dilution cycle; in comparison with those experiments the construction of the new apparatus has now been simplified and improved, and the mixing chamber temperature lowered.

A refrigerator capable of operating both in evaporation and dilution modes is described. The refrigerator provides preliminary cooling of investigated samples down to a starting temperature of about 0.3 K and permits the location of samples directly in the mixing chamber as well as their replacement

A 3He/4He dilution refrigerator is described where the instreaming 3He is precooled and liquefied by a counterflow heat exchanger which makes use of the enthalpy of the cold 3He gas pumped out of the still, and by subsequent Joule-Thomson expansion. This condenser replaces the usual 4He condenser.
