Specifying this part
What this model has to survive, and what it needs around it
Match the controller to the drive type
MC-NewtonLT drives coarse inertial stages (Linear, Rotator, Goniometer) in 1- and 6-channel versions over USB and TCP/IP. MC-ArchimedesLT drives scanners with sub-millivolt output noise. Only the .03.Ultra closes a capacitive loop, sampling at 50 kSa/s over EtherCAT, EtherNET or USB 3.0.
Automation
LabVIEW, C++ and Python APIs are supplied, so the stage can be sequenced from the same script that runs the measurement rather than driven by hand between points.
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.
