Abstract

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. The unit is based on classic motor-gear concept with nut and screw; different materials and lubrications have been tested for the same design configuration to compare performances. Load capability is above 20N. This paper describes main design features, results of different lubrications tested, tested performances, and main lessons learned.
