- | ==== He3 Insert | + | For reaching the lower (or higher) temperatures than CC cryostat can do, we use CCR top loading cryostats. They can be also booked without a special insert, if user needs quick sample exchange during the experiment. They cannot reach 2.5K as CC cryostat, their minimum temperatures are normally around 3K. |

+ | === Dilution Insert (for CCR) === | ||
+ | |||
+ | He3 insert can reach temperatures from 1K down to 80mK. Without running the dilution, it is possible to reach temperatures above 3K. But reaching stable temperatures between 1-3K is not possible. Cooling time to base temperature is roughly 6 hours. Running dilution insert requires serious effort of the sample environment team. | ||
