- | {{: | + | |
+ | 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. | ||

- | http://www.mlz-garching.de/ | + | Following special inserts are available for CCR cryostat from the pool. They need to be booked in advance. |
- | == * 5T magnet JVM1-5.0T | + | === He3 Insert |
- | http://www.mlz-garching.de/ | + | He3 insert can reach temperatures from 300K down to 0.35K. Cooling time to base temperature is 3-4hours. Currently running He3 insert is very automatized and is used on PANDA very often. |

- | {{: | + | === 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. |
