Instrumentation for laboratory diffraction measurements
Fundamental studies on the use of advanced X-ray sources (rotating anode sources) and optics (X-ray lenses and X-ray mirrors) for stress, texture and diffraction-line broadening measurements are conducted. Systematic investigations of the instrumental aberrations in parallel beam laboratory diffractometers have led to the development of corrections procedures for instrumental aberrations (see figure below). The use of non-ambient stages for stress and texture measurements is another focal point of interest. Calibration procedures for the true specimen temperature have been developed.
Details of the beam path with indication of the optical components and reference systems used for the Monte-Carlo ray-tracing of the diffractometer optics for a parallel-beam diffractometer based on a polycapillary collimator ('X-ray lens').
