X-ray Metrology with Synchrotron Radiation

Utilisation of synchrotron radiation in the X-ray spectral range for basic and applied metrological tasks with main focus on radiometry:

• Realisation of radiometric units by using the primary source standard BESSY II as calculable source of synchrotron radiation according to Schwinger's theory and cryogenic radiometers as primary detector standards
• Calibration regarding radiometric measurands for dissemination of the units by transfer detectors
• Characterisation and quality assurance of optical components and assembled systems in particular the x-ray regime
• Investigation of nanolayers and particles applying x-ray reflectometry and small-angle scattering
• Development and application of reference-standard-free x-ray fluorescence analysis
• Photon diagnostics and materials research at x-ray lasers
