Supporting injector operation with the FAIR settings management system

The FAIR Settings Management System is in productive use at the GSI accelerator facility. The core of the system is developed in collaboration with CERN and is based on CERN’s Software Architecture (LSA) framework. It is currently used at GSI for operating the synchrotrons, storage rings, and transfer lines. As part of the Injector Controls Upgrade project, which aims to integrate the Unilac linear accelerator into the new control system, concepts for scheduling parallel particle beams are being further realized. In preparation for the integration of the FAIR facility, existing concepts are being reviewed, refined and implemented. A key milestone for the upcoming implementation steps is the operation of Unilac with the new control system during the beam time 2026, with preparatory beam tests starting in summer 2025. This paper describes the current implementation status.
