TY - CONF AU - Pfeiffer, Sven TI - Status of the design and simulations for the FOFB of PETRA IV PB - KIT North Campus M1 - PUBDB-2025-05024 PY - 2025 AB - PETRA III is one of the most important facilities at DESY. The PETRA IV project aims to replace PETRA III with an ultra-low emittance ring (20 pm), add a new experimental hall in two additional octants and replace DESY II with a new low emittance booster. In this way, the emittance will be reduced from 1300 pm to 20 pm. A brief overview of the activities on the way to a stable beam orbit will be given. The following points will be introduced during the presentation: The stability task force, the system modelling and hardware design, the perturbation and noise models used and the SISO simulation as a first step towards a full ring simulation. Finally, we will conclude the presentation.
