European Synchrotron Radiation Facility
BM20 - The Rossendorf Beamline

The Rossendorf Beamline @ ESRF is a hard X-ray beamline dedicated to actinide research. Four experimental stations in an alpha-lab environment allow to perform X-ray absorption and emission spectroscopies as well as scattering techniques, including bulk-sensitive XAFS, XES, RIXS, powder and single crystal XRD, as well as surface-sensitive RAXR and CTR. Np, Pu, Am, Cm and Cf can be handled in the mg-range up to a total activity of 185 MBq.

Although dedicated to fundamental and applied actinide research, The Rossendorf Beamline is also open to research  on stable elements, including chemistry, catalysis,and materials science. Due to its very low detection limits for XAFS and XES, it is also well suited for environmental studies at low concentrations (a few ppm).

The Rossendorf Beamline has been built 1996-1998 by the former Forschungszentrum Dresden-Rossendorf which became (HZDR) at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The beamline is operated since then by the HZDR as a so-called CRG beamline (Collaborative Research Group). Two-third of beamtime is used for in-house research, while one third is provided for experiments selected by the scientific advisory committee of the ESRF.
