Summary

The authors present data and constructional details of a helium 3-helium 4 dilution refrigerator where a commercial two-stage Gifford-McMahon closed cycle refrigerator (Leybold RGD 510) precools the dilution unit, and thus this refrigerator does not require any external supply of liquid nitrogen or helium. The lowest temperature reached in the mixing chamber was 42 milliK at a helium 3 flow rate of 0,0001 mol/second.
