Technology Description

The Cryogenic Submicron Linear Actuator (CSA) is a medium range (±5 mm) submicron resolution linear actuator suitable to be used at cryogenic temperature (12K). The unit has been developed for fine positioning use. Load capability is above 30N. The unit has been developed for fine positioning use. Can offer a complete satisfaction to its clients due to it has been accomplished the development of a linear actuator with extensive cryogenic testing and strict configuration control to ensure product performance repeatability in manufactured units, providing a reference frame for current and future cryogenic fine positioning developments in cryogenic and space environment. 

Innovations & Advantages

The use of rotary or linear mechanisms in cryogenic environments is always a matter of concern due to the intrinsic cryogenic design complexity and testing constraints. The entity has completed the development of a linear actuator with extensive cryogenic testing and strict configuration control to ensure product performance repeatability in future manufactured units, and to provide a reference frame for current and future cryogenic fine positioning developments.
