Scope of the workshop

The aim of the proposed workshop is to gather both experts and novices in the field of actinide speciation using a variety of synchrotron techniques, as well as other advanced spectroscopic methods and theoretical simulations. We will assess and discuss the current status, potential, and future prospects for these partly well established, partly emerging techniques. AnXAS is also a platform for actinide beamlines at synchrotron light sources around the world, providing the latest information on new installations and upgrades. The focus of this workshop will also be to strengthen the ESRF based user community in actinide sciences, define future research directions and guide the worldwide efforts to build new dedicated end-stations.


AnXAS is a series of unique international workshops, which focus on basic and applied research of radioactive materials using synchrotron-based techniques. The workshops have been held in France, USA, Germany, Japan, Switzerland, and the UK. In 2022, the workshop shall come back to where it started in 1998, the ESRF, where the EBS along with the new ROBL-II provide an excellent meeting background.
AnXAS will be combined for the first time with ATAS, an International Workshop on Advanced Techniques in Actinide Spectroscopy, which has been held since 2012 in Germany, USA and France. ATAS is particularly focusing on complementary application of various spectroscopic techniques and their combination with theoretical approaches for a profound understanding of structures, thermodynamics and kinetics of f-elements complex formation.
Both workshops have been delayed due to CoVid from their usual tri- (AnXAS) and bi-annual patterns, and should take place again in 2022. Both serve similar communities and this combined event in 2022 will certainly improve synergistic effects and foster the scientific discussion between spectroscopists and theoreticians. Furthermore, scheduling conflicts in 2022 will be avoided.
