Piezo Atto Scanner
This cryogenic scanner uses piezo-resistive s-benders to move in a
200 micron scan area with sub-micron
precision at temperatures as low as 10 mK. A 'diving board' z-bender
moves the sensor into contact with the sample.
A set of attocubes with a
stick-slip piezo motion allow the scanner to move over a 5mm by 5mm total
area.
A variety of sensors can be mounted to the z-bender. In my case I use a
SQUID, Superconducting QUantum Interference Device, sensor. SQUID's are
very sensitive magnetic flux detectors. The SQUID-scanner combination
allows me to make magnetic maps of materials.
