I just thought I would throw this out there, see if anyone knows of some good products or neat tricks.
We are building a probe to be used with some DC SQUIDs that are going to be operating at low temp (~4 - 40K). For part of the design we want some sort of actuator or motor that would allow us to make contact with the sides of the chamber, probably somewhere on the order of a cm of displacement.
We have thought about using piezoelectric materials, but what I've seen so far only seems to have a displacement of a couple microns. Even wedged against the base of the material this would produce a cm of displacement.
We have also thought that there maybe a sort of pneumatic device that could do this, something designed for low tempurature, but, thus far I haven't been able to find anything.
Finally we thought of perhaps using some kind of magnetic device, but decieded to rule this out for fear of screwing up the readings from the SQUIDs.
Mostly we are looking for a product to buy, since we are going to be overloaded with building this probe and the machine to go with it, but, all ideas or suggestions are welcome
