S2

LOW-VIBRATION CLOSED CYCLE

CRYOSTAT

 

Complete low vibration, cryogen-free cryostats have been developed at S2 Corporation for either Pulse Tube or Gifford-McMahon cryocoolers. The system is designed for removable radiation shield and vacuum shroud windows that can be easily changed without disassembling the cryostat. Quick and easy access allows sample changes with minimal down-time. These systems are covered by multiple patents which are listed on our patents page.

 


Advantages of the Vibration Isolation System include:

  • < 100 nm Peak-to-Peak Vibrations (see chart below)

  • 500x Vibration Reduction of 1.4 Hz Pulse Tube Cycle

  • Operating Temperature Range: 3 K – 350 K

  • Rapid Sample Change and Turn Around Time

  • Sample Space Dimensions: 2.375 in. diameter x 2.5 in. length

Typical performance specifications, showing the measurement of a vibration dampened sample on a running Pulse Tube cryostat (red), as compared to a stock system without modification (green), and compared to vibration with cryostat off (blue).

Please inquire about custom tailoring this technology to fit your unique application requirements. 

RETROFITTING OF MOST MODELS IS POSSIBLE.

SAMPLE SPACE DIMENSIONS CAN BE CONFIGURED UPON REQUEST. PLEASE INQUIRE IF YOUR CRYOCOOLER HEAD OF CHOICE IS NOT LISTED.
