 ==== CC Cryostat (liquid-free) ====
-liquid-free CC is the working-horse on PANDA for experiments above 2.5K. To reduce background, a vacuum chamber wich large diameter is available.
+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 ====
-==== He3 Insert (for liquid-free CC 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.

+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.
