Application context
Why this design is used
Managing piezo self-heating
Remove the dissipation of driven axes so base temperature is not lost during scanning.
Strain-free thermal anchoring
Flexible braid decouples thermal contact from mechanical load on the positioner stack.
Specifying this part
What this model has to survive, and what it needs around it
Heat sinking a stage that has to move
High-purity copper braid ties the moving body to the cold plate, conducting heat away from the stack without restraining travel or introducing mechanical strain into the positioner.
Heat load at the cold plate
Stick-slip inertial drives dissipate energy per step and draw no holding current once stopped, so the steady-state load on the mixing chamber is the wiring loom rather than the motor. Anchor the loom at each temperature stage and thermalise the moving body with an FTC copper braid.
Non-magnetic construction
Titanium bodies (BeCu on the .ULT variants) and BeCu fasteners throughout, rated for operation to 35 T and down to 30 mK with the .ULT option, at 2 × 10⁻¹¹ mbar with .UHV. A single steel screw substituted at installation is enough to compromise a high-field assembly.
