| Abstract |
The 'Facility for Anti-Proton and Ion Research' (FAIR) presently under construction, extends and supersedes GSI's existing infrastructure. Its core challenges include the precise control of highest proton and uranium ion beam intensities, the required extreme high vacuum conditions, machine protection and activation issues while providing a high degree of multi-user mode of operation with facility reconfiguration on time-scales of a few times per week. To optimise turn-around times and to establish a safe and reliable machine operation, a comprehensive suite of semi-automated measurement applications, as well as fully-automated beam-based feedbacks will be deployed, covering the control of orbit, Q/Q', spill structure, optics, and other machine parameters. These systems are based on the LSA settings management framework, code-shared with and also used at CERN. The concepts, software architecture and first prototype beam tests at the SIS18 in 2016 are presented. As an initial proof-of-concept, a cycle-to-cycle orbit* and macro-spill feedback, as well as a semi-automated magnetic quadrupole- and sextupole-centre measurement tool have been selected.
