Closed Cycle Cryostat - Ultra Low Vibration 3-5 nanometer


The X-20 interface uses a Helium exchange gas to decouple the sample space from the cold tip of the cryocooler. This prevents almost all vibration from being transmitted from being transferred to the sample space. Scientists have demonstrated vibration levels as low as 3-5nm with the CS202*E-DMX-20.

1. The Cryocooler is supported by a Floor stand
2. The soft rubber bellows minimize the vibrations transmitted to the sample while keeping in the Helium exchange gas.
3. The X-20 interface has no contact with the cryocooler except through the rubber bellows.
4. The Cold tip has 10-30 micron vibrations (depending on CCR model) but no direct contact with sample space.
5. Convective pockets of Helium exchange gas cools the sample space.
6. The Sample only in contact with X-20 Interface
7. Windows for optical Experiments
8. The X-20 interface is mounted directly on a (user provided) Vibration Isolation Table

Features:

  • <4.2K to 800K Closed Cycle Nanometer Displacement Low Vibration Interface
  • Vibration dampening interface which provides <3 to 5 and <10 to 15 nanometer displacement at the sample.
  • Interface is compatible with DE-202 / DE-204 and DE-210 so that the temperature range and cooling capacity that best meets the experiments requirements can be used.
  • Modular design allows easily interchangeable vacuum enclosures for multiple applications.
  • Allows easy removal of the cryocooler's cold head without breaking vacuum or disturbing a complicated sample setup for chamber baking to 200C or cooler maintenance.
