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.

The bi-annual "VUV and EUV Metrology" event took place on 19 and 20 October 2017 for the fourth time; it was organized at the Hermann von Helmholtz building within the scope of the 304th PTB Seminar. With more than 35 presentations and posters, the wide range of topics addressed spanned from the industrial application of EUV radiation to the manufacturing of semiconductor structures, to the...

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...
