Pressure applied in a particular direction is a very useful tuning parameter in case material response is expected to be anisotropic. For this reason we have developped a uniaxial pressure device that is capable of in-situ tuning, force measurement and feedback mechanisms to maintain it constant.
Key parameters:
Force up to 200 N
Pushing and pulling available
Opening angles are 40 degrees on 4 different sides
Compatible with SINQ magnets MA10 and MA2 and the ORI2 cryostat
Optimal sample sizes for experiments:
Push and pull: 1.7x1.7x9 mm3 and 1x1x6mm3,
Push-only: 2x2x6 mm3 and 1x1x4 mm3
