Introduction

Many applications in industrial and medical research as well as in fundamental research require cryogenic temperatures. Additionally, in many cases it is not only necessary to cool the samples but also to mechanically manipulate them precisely within the cryostat. SmarAct has developed stick-slip piezo actuators with low-heat profiles and ultra-high vacuum compatibility, which allow sample manipulation in temperatures down to the mK regime. Resistive cabling (based on phosphor bronze) is optionally available to reduce the heat load on the positioning stages. Additionally, they can be used at temperatures of up to 330 K and are bakeable at temperatures of up to +150 °C. For the use in high magnetic fields at cryogenic temperatures, non-magnetic versions are available. For high precision positioning under cryogenic conditions, such as quantum computing, SmarAct has developed cryogenic positioning stages featuring unmatched closed-loop positioning performance.
SmarAct’s cryogenic actuators can be easily assembled into complete positioning systems including thermalization management and customization to your specific application.
