The SOLEIL synchrotron is a secure industrial site and visits to the site are organized and planned in advance. Please enquire directly on the website about booking arrangements. If the site is fully booked, it's because we are. New slots open regularly, but usually fill up quickly. We do our utmost to welcome a large public, but are limited by the site's operation and available manpower. We welcome over 5,000 people a year and do our best to accommodate every request.
If you have any further questions, please write to visites@synchrotron-soleil.fr.
Thank you for your understanding.
