From the manufacturer’s website:


The Intelligent Cryo-Cycle Cryostat is the latest enhancement of the “hybrid” cryostat combining the advantages of electric cooling with the reliability of liquid nitrogen. The cryocooler is used to condense the boil-off N2 gas back into the 25-liter Dewar. This unique capability provides the convenience of operating a detector for up to two years before LN2 needs to be added, but at the same time keeps the detector cold in case of power failure. With the Intelligent Cryo-Cycle Cryostat, the LN2 supply keeps the detector cold for up to seven days without power. There is no interruption of cooling and, as a result, there is no down time due to partial warm up as long as LN2 is maintained. In addition, there is no risk of detector failure because of temperature cycling. LN2 lost during power outages may be replenished at any time.

The Intelligent Cryo-Cycle Cryostat is designed with the combined focus on optimal reliability and serviceability. Since the cooler is the critical part determining the reliability of the complete unit, Mirion does not compromise in this area. Proven with the unprecedented lifetime of the Cryo-Pulse® 5 Plus cooler as demonstrated in the field since 2006, Mirion had the new cooler developed by the same cryocooler supplier. Apart from State-of-Health (SoH) parameters already tracked in previous Cryo-Cycle versions, such as Dewar pressure and cooler power, even more parameters are now monitored and all of them are automatically logged in onboard memory. The monitoring and automatic logging of all the parameters will enable efficient servicing of the Intelligent Cryo-Cycle Cryostat
