DESCRIPTION

The Cryo-Cycle™ II cryostat is a unique offering in the field of cryogenically cooled radiation detectors. The Cryo-Cycle II cryostat 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 cryostat the LN2 supply keeps the detector cold for up to one week without power. There is no interruption of cooling. There is no downtime 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 cryostat comes with a number of improvements allowing us to answer our customers’ requirements even better.
Key Improvements
• Reduced cooler vibrations
• Improved LN2 level sensor probe
• Single front panel
• RS-232 and USB interfaces
• Alarm and autofill relay outputs
• A Graphical User Interface (GUI)
The audible noise has been reduced to less than 60 dB(A), measured at 1 m
distance, making the Cryo-Cycle II cryostat 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.
