SOLEIL Highlights 2020

Share

It is obviously impossible to summarize the year 2020 without mentioning the COVID-19 pandemic, which forced us all to change our way of interacting and working. However, the mobilization of all the SOLEIL teams has enabled us to limit the synchrotron's shutdown to 7 weeks, with users being welcomed back at the end of May 2020. The opening of SOLEIL is symbolized on the first page of this edition of our Highlights, in which we offer you a selection of the most outstanding results published in 2020.
