Description

The SPIRAL2 heavy ion accelerator is currently undergoing several extension projects under development. In Phase 1+, the DESIR experimental hall will receive very low energy radioactive ion beams from S3 or SPIRAL1. In Phase 1++, a new cryogenic ion source and a new injector will be implemented to broaden the range of heavy ions currently accelerated.
This contribution presents the integration of these new facilities into the SPIRAL2 PLC-based control system. The integration builds on recent technological upgrades while maintaining system consistency and ensuring compliance with the specific constraints related to radiation protection and operational safety. Some existing PLCs have been extended, and new ones have been added to automate processes related to beam operation (machine protection system, equipment insertion, vacuum, RF, cryogenics), building infrastructure (nuclear ventilation, refrigeration, alarm management), and nuclear safety (access control units, radiation monitoring).
This integrated approach ensures a coherent, maintainable control system that supports safe and efficient operations for the DESIR and Newgain projects.
