This condensation stage has the great advantage, that the dilution refrigerator can work without a separate 1 K stage (for example, a cold plate or a pumped He 4 bath). This one dispenses with a pumping line and a rotary pump. This stage is ideally suited for runs of long duration.

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
