CS210-GMX-20

The CS210F-GMX-20 pairs our largest cryocooler, the DE-210, with our X-20 ultra low vibration interface to offer unprecedented cooling power at nanometer vibration levels.

The CS210F-GMX-20 uses a helium exchange gas to decouple the sample space from the cold tip of the DE-210 cryocooler. This prevents almost all vibration from being transferred to the sample space. Scientists have demonstrated vibration levels as low as 3-5 nm with the CS210F-GMX-20.

Because the exchange gas is inherently less efficient than cooling by conduction, the base temperature of the sample will be 1-2 K higher than the cryocooler. Additionally the DMX-20 interface requires the cold tip oriented downward to facilitate convective cooling of the exchange gas.

The CS210F-GMX-20 is ideally suited for Mössbauer experiments and vibrationally sensitive transport measurements. For optical microscopy applications such as Micro Raman, Micro PL, and quantum dots, the CS204F-DMX-20-OM is preferred. The -OM modification is also available for the GMX-20.
