【 摘 要 】

ROCK is a new beamline at SOLEIL dedicated to Quick-EXAFS measurements. The optical layout has been optimized to get full advantage of the monochromators, which were designed at SOLEIL and successfully used at SAMBA from 2009 to 2014. ROCK has started user operations since March 2015. It is mainly employed to monitor fast kinetic processes in materials used in catalysis and energy sciences. A review of the ROCK performances and capabilities is presented. The high automation achieved for fast change of monochromators, optimization of mirrors for harmonic rejection and detectors allows the simultaneous operando characterization of different chemical elements present in a material during the same reaction.
