The CS204F-DMX-20 opens up a wide range of capabilities never before possible with a closed cycle cryocooler. The CS204F-DMX-20 uses a helium exchange gas to decouple the sample from the cold tip of the DE-204 cryocooler. This prevents almost all vibration from being transmitted to the sample. Scientists have demonstrated vibration levels as low as 3-5 nm with the CS204F-DMX-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 a downward orientation of the cold tip to facilitate convective cooling of the exchange gas.
The CS204F-DMX-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. CS204-DMX-20低溫冷卻系統 特點:
