Websystem before the cryocooler starts. The heat pipe, the inner vessel and every flow path in the system has to be purged by 200 kPa dry nitrogen gas, and evacuated to 10-4 Torr of high vacuum. The test starts with a chill down process using LN 2 to cool the inner vessel to save cool-down time, as opposed to using the cryocooler refrigeration power. WebStored cryogen systems should be used with passive cooling (such as sunshades) to extend the life of the cryogen. Stored cryogen coolers can also be used with ADRs to reach temperatures below 1 kelvin. On XRS, for instance, a liquid helium bath was used with an ADR to reach 60 millikelvin.
