MPD (Materials Powder Diffractometer) is suitable for the analysis of polycrystalline samples at room temperature. This diffractometer has a vertical theta-theta goniometer (240 mm radius), where the sample stage is fixed and does not rotate around omega axis as in omega-2theta diffractometers. Two different configurations are available: Bragg-Brentano and Transmission configuration. Applications: Identification of crystalline phases in organic and inorganic compounds, Quantitative phase analysis in organic and inorganic compounds, Particle size determination.

X-ray source: Cu Κα radiation (Κα = 1.54187 Å)

The detector used is an X’Celerator which is an ultra-fast X-ray detector based on Real Time Multiple Strip (RTMS) technology

Air and Room temperature experiments

Available capillary measurements for air-sensitive samples, liquids, or small quantities of powder.

The MRD (Materials Research Diffractometer) is suitable for the structural characterization in thin-films materials at room and high temperature. This diffractometer has a horizontal ω-2θ goniometer (320 mm radius) in a four-circle geometry and it works with a ceramic X-ray tube with Κα anode (λ=1.540 Å). This diffractometer is equipped with different incident and diffracted optics which can be interchanged depending on the application required (i.e. a parabolic mirror, a hybrid monochromator, a Ge(440) four-crystal monochromator, a parallel plate collimator, and a polycapillary lens). Applications: 1) Crystal structure analysis: phase identification, determination of cell parameters, domain orientation and stress on thin films. 2) θ-2θ measurements (normal and high resolution) in epitaxial and polycrystalline thin-films. 3) X-ray Reflectivity measurements for estimation of thickness and roughness. 4) Rocking curves measurements. 5) Reciprocal Space Mappings. 6) Texture analysis (Phi and pole figures measurements) 7) Grazing incidence measurements.
