Abstract

The design and construction of a beamline dedicated to X-ray absorption spectroscopy, X-ray fluorescence analysis, X-ray diffraction and X-ray small-angle scattering measurements with micron and submicron spatial resolution in the photon energy range of 1.9–30 keV are reported here. The main feature of the beamline is a combination of all these methods in one experimental station. The source will be a BESSY 7-T wavelength shifter, which is already in operation. Such a wavelength shifter with its continuous spectrum is an optimum source for these experiments. Glass capillaries and the combination of a linear Bragg–Fresnel lens and bimorph mirror were chosen as the special optical components in the beamline. This beamline will open for BESSY users the possibility to perform experiments on the same sample applying a microfocused X-ray beam in combination with advanced experimental methods.
