Crystals in a Pink X-Ray Beam (IMAGE) Deutsches Elektronen-Synchrotron DESY Caption A newly developed set-up tremendously reduces background scattering in X-ray structure analysis of biomolecules like proteins at synchrotron X-ray sources. Scattering often hampers high resolution structure determinations. To achieve this, the X-ray beam (highlighted in pink) is enclosed in thin metal capillaries shortly before and behind the sample and the air immediately surrounding the sample is replaced by a stream of helium gas.
