For more than 25 years, the Physikalisch‐Technische Bundesanstalt has been strongly
engaged in the field of metrology using synchrotron radiation. In Berlin, this research …

This review describes the efforts of several national metrology institutes to replace the
present definition of the kilogram by a new one based on the mass of a given number of 12 …

The first hard X-ray beamline at BESSY II will be installed by BAM and PTB at a
superconducting 7T wavelength shifter. The main optical elements of the beamline are a …

During the past decade, high-accuracy soft x-ray radiometry has increasingly gained in
importance. In particular, its routine availability is a prerequisite for the development of …

A dedicated in-vacuum X-ray detector based on the hybrid pixel PILATUS 1M detector has
been installed at the four-crystal monochromator beamline of the PTB at the electron storage …

Monochromatized synchrotron radiation of the electron storage ring BESSY II has been used
for the non-destructive thickness determination of nanolayered materials by two different …

The development of EUV lithography, has made high-accuracy at-wavelength metrology
necessary. Radiometry using synchrotron radiation has been performed by the German …

For the accurate determination of the Avogadro constant, two 28 Si spheres were produced,
whose macroscopic density, in addition to other values, must be determined. To make a …

The accuracy of detector calibration in the UV, vacuum-ultraviolet, and soft-x-ray spectral
ranges could be significantly improved by the use of the synchrotron radiation electrical …
