Au prix d’un effort considérable des SYNCHROTRON SOLEIL lignes pour absorber ces reliquats -dont la quantité est souvent HIGHLIGHTS 2020 liée à la proportion d’utilisateurs étrangers accueillis par la ligne- leur nombre Est descendu de 224 projets en juillet 2020 à 54 en Captions/Légendes avril 2021. 1 ---------------------------- Activity resumed on the beamlines at the end of May.

Ici sur ODE (à gauche) et AILES (à droite). As for industrial users, despite a drop in the number of hosted projects (see below), 2020 nevertheless represents the second-best year for SOLEIL, after 2019. In addition to this mobilisation to preserve the user programme and beamline activity, the drafting of a Preliminary Design Report initiated by SOLEIL teams in 2019 for the upgadigof the Synchrotron's facilities has been actively pursued. The aim is to ensure that SOLEIL remains competitive and to extend its lifespan by at least 15 years beyond 2032. This upgrade will make it possible to meet current scientific and societal challenges, by rebuilding the storage ring to obtain electron beams with a record emittance of 50 x 50 pm.rad, producing photon beams at 2 orders of magnitude brighter than at present, and by adapting the beamlines. With this upgrade, access to nanometer scale and process dynamics would be possible for most techniques, and entirely new methods could be developed. Naturally, it will be combined with the development of IT resources in a data-centric architecture. The very design of future accelerators considers environmental concerns, as it is planned to reduce the power consumption of the storage ring by half. To optimise costs, the existing infrastructure will be preserved whenever possible. The replacement of the ageing infrastructure will minimise its energy footprint. In December, a first draft of the Conceptual Design Report was presented to the members of the Scientific Advisory Committee and then to the SOLEIL Board. As of now, SOLEIL is building its long-term strategy for storing, analysing and sharing experimental data: the aim is to have the necessary infrastructure and tools available locally for the reduction and initial analysis of the data produced, in order to judge their quality and make the right decisions during an experiment, and to rely on external centres for the subsequent stages of analysis and conservation of online accessible data. In this context, SOLEIL is the first use-case of FITS (Federated Information Technology services for Research Infrastructures), a project that brings together CC-IN2P3 and IDRIS around a coordinated infrastructure for storing, 5
