We will observe the evolution of the hkl reflections of choice from room temperature, where CoO shows rock salt structure, to a target temperature below TN (293 K). The temperature will be controlled through external cooling using a N2 cryo-stream. The study will be performed through RSM and imaging of the 3D structure of the CoO sample trough mosaicity and strain maps in the ID06-HXM beamline in transmission mode. The single crystals are 5 mm x 5 mm x 50 um . The investigated reflections are the (100) and (111).
