As requested by its Board in December 2018, the year 2019 saw the beginning of work on a Conceptual Design report to prepare for the upgrade of SOLEIL’s installations. This work was done in parallel with the experiments which continue to be carried out on the - now - 29 beamlines of the synchrotron. Here is a selection of the most striking scientific results published in 2019. |
