• The workshop will be held onsite – personal attendance of all participants is requested.
• The number of participants will be limited to 100.
• All participants are encouraged to submit an abstract (talk or poster).
• Contributions from all disciplines of spectroscopy and computational chemistry relevant to actinide and radionuclide science are highly welcome.
• The workshop includes a visit to the KIT Light Source onsite KIT Campus North as well as synchrotron radiation facility reports / discussions.

ATAS - AnXAS 2024 at KIT will be the second joint workshop since merging the formerly seperate ATAS and ActinideXAS series in 2022. Both workshops date back to original initiatives by Helmholtz-Zentrum Dresden-Rossendorf (HZDR).

ActinideXAS was initiated in 1998 at the ESRF in Grenoble (France) to focus on work at emerging dedicated synchrotron labs licensed to handle actinide materials at beamlines. The follow-up events took place at LBNL (USA), FZK (Germany), SOLEIL (France), SPring-8 (Japan), PSI (Switzerland), and Oxford University (UK).

The series of ATAS workshops started 2012 at HZDR in Dresden (Germany) in the context of a comprehensive round robin test comparing actinide speciation methods at labs around the world – followed by events at HZDR, PNNL (USA) and Nice (France). ATAS extended the scope to other advanced, not solely synchrotron-based speciation methods, with an additional emphasis on quantum chemistry.

The first joint workshop was held in 2022 – again at the ESRF in Grenoble – feeling the strong need to catch-up with personal exchange between experts and novices in the fields of actinide science, radionuclide speciation, spectroscopy and theory after the forced break due to the pandemic. As from the beginning the audiences of both ATAS and ActinideXAS had been largely overlapping, the scientific advisory boards decided to keep the format for now as extended five-day joint workshop.
