X-ray diffractometer (Panalytical X’PERT PRO)

Technical Data

X-Ray tube: Ceramic Cu X-ray tube, power capability of 2 kW, water cooling, "long fine focus", elimination of Kβ (Ni filter)
Goniometer: Vertical goniometer of Θ-Θ geometry, independent Θ and 2Θ driving gears, angle range from 0.2o, possibility to change the diameter of the goniometer, angular precision 0.001o
Optics: Optical modules at the primary and secondary beam: slits and colimators for diffractometry and reflectivity measurements with three computer operated elements; possibility to measure with Goebel mirror; the PreFix system allows easy exchange (no re-alignment) of details
Detectors: Proportional detector for reflectivity measurements; real time multiple strip detector for xrd measurements allows to obtain ultrafast data collection
Others: The high-temperature chamber designed for measurements at temperatures up to 1200oC;
Open Eulerian Cradle for investigations of stress and texture;
Capillary spinner for transmission measurements;

Application

Thin film and multilayer reflectometry and grazing incidence diffraction; investigations of stress and texture; mapping of reciprocal space
