Cryo-Cycle - Model II -Hybrid Cryostat Cooled Radiation Detectors
The CANBERRA Cryo-Cycle II is a unique offering in the field of cryogenically cooled radiation detectors. The Cryo-Cycle II is described as a “hybrid” cryostat because it combines the advantages of electric cooling with the reliability of liquid nitrogen. The long-life Pulse-Tube cryocooler, condenses the boil-off N2 gas back into the 25 liter Dewar. This unique capability provides the convenience of operating a detector for 12 to 18 months before LN2 needs to be added, but at the same time keeps the detector cold in case of power failure.
With the Cryo-Cycle II the LN2 supply keeps the detector cold for up to one week without power. There is no interruption of cooling. There is no down-time due to partial warm-up as long as LN2 level is maintained. There is no risk of detector failure because of temperature cycling. LN2 lost during power outages may be replenished at any time. The Cryo-Cycle II comes with a number of improvements allowing us to answer our customers` requirements even better.

The audible noise has been reduced to less than 60 dB(A), measured at 1 m distance, making the Cryo-Cycle II well suited for application in quiet laboratory environments.
The new LN2 level sensor probe provides better accuracy. The measured LN2 level is displayed through a continuous LED indicator scale on the front panel, allowing to better schedule periodic refills.
