ROBLâII at ESRF: a synchrotron toolbox for actinide research
ROBLâII provides four different experimental stations to investigate actinide and other alphaâ and betaâemitting radionuclides at the new EBS storage ring of ESRF within an energy range of 3 to 35â
keV. The XAFS station consists of a highly automatized, high sample throughput installation in a glovebox, to measure EXAFS and conventional XANES of samples routinely at temperatures down to 10â
K, and with a detection limit in the subâp.p.m. range. The XES station with its five bentâcrystal analyzer, Johannâtype setup with Rowland circles of 1.0 and 0.5â
m radii provides highâenergy resolution fluorescence detection (HERFD) for XANES, XES, and RIXS measurements, covering both actinide L and M edges together with other elements accessible in the 3 to 20â
keV energy range. The sixâcircle heavy duty goniometer of XRDâ1 is equipped for both highâresolution powder diffraction as well as surfaceâsensitive CTR and RAXR techniques. Single crystal diffraction, powder diffraction with high temporal resolution, as well as Xâray tomography experiments can be performed at a Pilatus 2M detector stage (XRDâ2). Elaborate radioprotection features enable a safe and easy exchange of samples between the four different stations to allow the combination of several methods for an unprecedented level of information on radioactive samples for both fundamental and applied actinide and environmental research.ROBLâII at ESRF provides four experimental stations to investigate actinides with Xâray absorption and emission spectroscopy, and with surface, highâresolution powder, and singleâcrystal Xâray diffractometry
