Complete low vibration cryogen-free cryostats are now available from 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.

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).

Innovative Vibration Design is easily applied to both Pulse Tube and GM configurations. (Pulse Tube configuration shown)
