On B18, the Core-XAS beamline at DLS we have developed an emission spectrometer for the collection of high resolution X-ray emission spectra using the Von Hamos configuration. Design considerations, performance and experimental results will be presented.

Highly Annealed Pyrolytic Graphite (HAPG) was developed around 10 years ago by the Company Optigraph. Soon, first experiments demonstrated its potential for high resolution X-ray spectroscopy, namely X-ray Absorption Spectroscopy (XAS) and X-ray Emission Spectroscopy (XES). Meanwhile, spectrometer for XAS as well as for XES are in operation, which use X-ray tubes as sources and are suitable...

In high-resolution X-ray Emission Spectroscopy (XES) crystal-based Wavelength-Dispersive Spectrometers (WDS) are being applied for characterization of nano- and microscaled materials. Thereby the so called von Hamos geometry provides high detection efficiency due to sagittal focusing using cylindrically bent crystals. To maximize the detection efficiency a full-cylinder optic can be...
