Based on specific beam characteristics (emittance, coherence, variable polarization) and several X-ray diffraction (XRD) techniques applied (resonant, reflectivity) on single crystal and thin films under extreme conditions (temperature, pressure), the product is expected to fast progress the investigations of magnetic materials at nanoscale level. The dedicated machine (diffractometer) will be in one of the newly constructed experimental enclosure (G) of a main beamline (POLAR) in the 4th (ID-4) sector, serving a large spectrum of investigations for Magnetic Material (MM) group. POLAR-Dm was conceived on a traditional 6C (C-circles) geometry, maintaining the common kinematic structural principle of its family. With the addition of several interchangeable positioning devices (e.g., Euler cradle, air bearings stages, etc) the system is expanding the spectrum of possible investigations, maintaining the precision of new setups. The kinematic, design and precision concepts applied, together with the obtained test results are all in detail presented.
