ROBL – The Rossendorf Beamline at ESRF

Research at ROBL

The Rossendorf Beamline as a beamline at ESRF (European Synchrotron Research Facility) is dedicated to molecular actinoid sciences. Elements such as uranium, plutonium and other f-block metals are subject of intense research contributing to scientific progress in nuclear waste management. In this context a variety of high-performance tools, e.g. EXAFS-Spectroscopy (extended X-ray absorption fine structure) and HRXRD (high resolution X-ray diffraction) are used to determine structural parameters for the near-neighbor environment of actinides. This includes aqueous speciation as well as the complexation with dissolved inorganic ligands like chloride, sulfate or nitrate, complexation with organic ligands like acetate or humic acid and the interaction with bacteria, plants and their sorption to mineral and rock surfaces. In this way HZDR-researchers are engaged in fundamental as well as applied radioecological research.

ROBL set-up for users

The HZDR scientists at ROBL are responsible for the operation of two experimental Radiochemistry hutches (RCH-I and -II). Beamtime is being offered to in-house and external users upon scientific merit of the submitted proposal, which is evaluated by review panels of HZDR or ESRF.

ROBL was a pooled Facility of ACTINET/TALISMAN from 2004 through 2015 and provides AcReDaS, the spectroscopic database for actinoids and other elements.

Operators and funding

As a collaborating research group (CRG) beamline (BM-20 ROBL) ROBL is located at the ESRF in Grenoble, France. It has been operated by the HZDR since 1998 and receives additional support from the German Federal Ministry of Education and Research (BMBF) and the European Council.

Between 2016 and 2020 the HZDR is investing about four Mio. Euro to widen the portfolio of the experimental possibilities of ROBL for the actinide user community.
