The IRRAD beam operation in 2021 will follow the CERN Injectors Schedule approved on 02.12.20 and it is submitted to the completion of the ongoing consolidation works in the PS East Area.

The possibility of performing “urgent” irradiation experiments in 2021 (week 42 to week 45) will be confirmed by the end of June 2021 and, in positive case, the call for user experiments will be issued accordingly.

The IRRAD facility will resume its regular operation at the beginning of 2022.
