Many applications in science and industry require more than two degrees of freedom for positioning samples or components. Even at very low temperatures and in confined spaces, the payload must be moved with the highest precision.
SmarActs’ cryogenic positioning systems are modular, precise, customizable and thermally managed to keep your samples as cold as possible during positioning or scanning tasks.

The central component of any XYZ positioning system is a linear stage. In this example, an SLC-1720-CR. Three stages can be easily combined with holders and adapter plates to form compact multi-axis setups, which are usually connected to the cold finger of a cryostat in the customer setup.

When designing high-resolution positioning systems that need to operate accurately at cryogenic temperatures, it is important to ensure that the heat load from the stages is transferred to the cryostat as quickly as possible to reduce temperature creep of the positioning system due to thermal expansion of the stages and mounting components.

The most important task is to transfer the heat from the payload to the mounting base plate to ensure a constant and low temperature at the point of action.

Depending on the application, there are different designs of thermalization equipment to ensure optimal heat transfer to the cryostat. Three different setups are shown below as examples.
