Division 7

Highest accuracy and reliability of the realisation, maintenance and dissemination of units of radiation physics and thermodynamics, especially of the quantities spectral power of electromagnetic radiation, temperature, heat, pressure in vacuum. Development of new methods and techniques even in extreme areas, Advisory service and development of measuring systems for new metrological challenges


In the second week of October, the first Autumn School of the European X-ray Spectrometry Association (EXSA) coorganized by EXSA, PTB and TU Berlin took place in combination with a workshop and a meeting of the Fundamental Parameter Initiative. About 75 participants 25 students among them discussed on Quantitative Methods in X-ray Spectrometry.

At PTB's laboratory at the BESSY II electron storage ring in Berlin-Adlershof, proof has been furnished that even measuring fields with a size of a few micrometers can be characterized by means of small-angle X-ray scattering in a reflection geometry under grazing incidence. The signal overlap problem, which is due to the fact that the incident beam also illuminates the area surrounding the...
