+ | ===== Cryostats ===== | ||
+ | |||
+ | ==== CC Cryostat | ||
+ | |||
+ | liquid-free closed cycle (CC) cryostat is the working-horse on PANDA for experiments above 2.5K and below 320K. To reduce background, a vacuum chamber with large diameter is available. To mount the sample, we need to open the whole cryostat, which means that sample exchange need additional 0.5 - 1 hour for drying the cryostat (depending on the inner temperature before exchange). This cryostat is dedicated to PANDA so it is available all the time and easy to use. | ||

+ | ==== CCR cryostat ==== | ||
+ | |||
+ | 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. | ||
+ | |||
+ | * {{: | ||
+ | |||
+ | Following special inserts are available for CCR cryostat from the pool. They need to be booked in advance. | ||
+ | |||
+ | === He3 Insert | ||
+ | |||
+ | 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 | ||
+ | |||
+ | 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. | ||
