The registration of user experiments for the run 2021 is open!

Deadline to submit your request is Monday August 2nd 2021. Due to the time constraints of this first run after the LS2, please note that late requests will not be considered.

The possibility to perform complex irradiation experiments, or the irradiation of heavy materials, will be limited during the short run 2021.
