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 phase (the concentrated phase) and a He-poor phase (the dilute phase). As shown in the phase … See more 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 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 cryogenic liquids is needed in these … 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 The cooling power (in watts) at the mixing chamber is approximately given by where See more • Adiabatic demagnetization • Magnetic refrigeration • Helium-3 refrigerator See more • Lancaster University, Ultra Low Temperature Physics - Description of dilution refrigeration. • Harvard University, Marcus Lab - Hitchhiker's Guide to the Dilution Refrigerator.
