Technical design concept and development of the new accelerator control and timing systems for PETRA IV

At DESY, extensive technical design and prototyping work is currently underway to upgrade the PETRA III synchrotron light source to PETRA IV, a fourth-generation low-emittance machine. The realization of the new machine necessitates a redesign of the accelerator’s control and timing systems. The primary hardware components will be based on the MTCA.4 standard, which has established itself as a reliable platform at DESY. The control system framework will be modernized to accommodate the demands of a fourth-generation light source. This paper presents the key decisions made in this context and provides an overview of the design and development process.
