Dilution refrigerator objectives
A He/ He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes. The dilution refrigerator was first proposed by … See more The refrigeration process uses a mixture of two isotopes of helium: helium-3 and helium-4. When cooled below approximately 870 millikelvins, the mixture undergoes spontaneous phase separation to form a He-rich … See more Modern dilution refrigerators can precool the He with a cryocooler in place of liquid nitrogen, liquid helium, and a 1 K bath. No external supply of … See more There is no fundamental limiting low temperature of dilution refrigerators. Yet the temperature range is limited to about 2 mK for practical reasons. At very low temperatures both the viscosity and the thermal conductivity of the circulating fluid become larger if … See more • Lancaster University, Ultra Low Temperature Physics - Description of dilution refrigeration. • Harvard University, Marcus Lab - Hitchhiker's Guide to the Dilution Refrigerator.
