Goniometer for cryomagnets - IRELEC

The goniostick is a precision goniometer specific to in-situ sample alignment (without removing the sample) on Neutron beamlines.

It is fully non-magnetic and features two orthogonal rotational motions that can be motorized.

The goniostick is delivered with Cernox and Pt100 temperature sensors located near the sample.

IRELEC proposes this equipment with a license agreement with the Institut Laue-Langevin (ILL).
