Interfacing your CRC cryocooler to the 4K plate of a Pulse Tube (PT) or Gifford-McMahon (GM) precooler
Our cryocoolers need to be interfaced to a cooling platform at 4K within a host cryostat. The interfacing can be designed to suit your particular application, with the CRC cryocooler positioned either on- or off-axis from the PT/GM head. Our standard 1K cryocoolers will run with mechanical precoolers having cooling power as low as 100mW at 4K. If your application requires vibration isolation the CRC cryocooler will need a separate mechanical support structure and a flexible thermal linkage to the precooler’s 4K stage.
Mounting radially on the precooler head
Useful for large experimental tables in a large host cryostat.
The circular interfacing plate can be customized to suit the particular needs of your application.
Mounting axially on the precooler head
Useful for small experimental tables in a small host cryostat.
The interfacing mount doubles as a radiation shield for the cryocooler pumps, improving cryocooler performance.
Mounting directly on the precooler head
Fewer thermal boundaries make this a desirable option where vibration isolation is not important.
The mainplate of the cryocooler can be custom-designed for your application.
Interfacing your CRC cryocooler to the 4K plate of a wet dewar cooled with liquid cryogens
Custom-shape mainplate and full radiation shield stand
The shape of the mainplate can be optimised to provide the maximum space for the end-user’s experiment.
The hole pattern in the mainplate can be designed to provide flexible use in different cryostats.
Separate radiation shield and supports
Radiation shielding of the pumps is provided by a shield that simply bolts to the cryocooler main plate.
Additional stainless steel struts support the cryocooler.
The cryocooler can be moved and placed in different positions to make best use of the available space in the cryostat.
Folded designs to sit directly on the 4K plate
For use in cryostats with limited working height, our cryocooler designs can be ‘folded’ to reduce the overall height.
Tell us the space you have available and we can optimise our design to fit within it.
