Application context

Why this design is used

Cryo-compatible assembly

BeCu screws and PEEK connectors rated for millikelvin and high-field service.

Avoiding magnetic contamination

Keeps ferromagnetic fasteners out of a system where a single steel screw distorts the field.

Field service and rebuilds

One kit covers the fasteners, connectors and drivers a stack needs during a cryostat opening.

Specifying this part

What this model has to survive, and what it needs around it

Hardware rated for the environment

BeCu screws in M1.6 and M2 rated to 30 mK and 35 T, PA connectors in 2, 3 and 4-pin, a Peek UHV connector set, plus driver and manual. Specified as a set because substituting standard workshop hardware is the usual way a non-magnetic assembly stops being non-magnetic.

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.

Open-loop vs closed-loop piezo

Why an open-loop piezo is wrong by 15 % of its travel, how creep grows with the logarithm of hold time, what strain-gauge and capacitive feedback actually fix — and the bandwidth and sensor noise a servo costs you in return.
