Summary

If a cryogenerator is used as precooler to avoid the helium 4 bath, it is possible to cool the input gas down to 2 K before the dilution unit, using Joule-Thomson expansion of the mixture at the dilution output. This results in a simple refrigerator with a low power dissipation at 4 K and continuous operation below 100 milliK. The working lifetime of the cryostat is limited by the quantity of gas. For six years of operation, the gas storage system should contain about 30 kg.
