Few new additions
Welcome to Florent Philippon from HSE/RP who takes over from Christelle
Saury. The team looks forward to working with you in the coming years –
enjoy the chaos.
The HiRadMat team would like to take this opportunity to thank Christelle for
her many years of hard work and dedication to the HiRadMat facility. Your
continuous support over the years was highly appreciated by both the
HiRadMat team and the users.
…..And finally, let’s welcome Pascal Simon to the HiRadMat Team.
