It could be a major step forward in building a plasma-based free-electron laser at multi-GeV beam energy but the validation of the concept requires experimental tests which could be partly carried out in the ATHENA project, comments Ralph Assmann, EuPRAXIA coordinator and DESY leading scientist for accelerator research and development, in whose group this work was performed.
