TI - PETRA IV Storage Ring Design J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - PETRA IV will be a diffraction-limited 6 GeV synchrotron light source with an emittance of 20 pm rad at DESY Hamburg. The TDR phase is nearing completion, and the lattice design is being finalised. The lattice will be based on the six-bend achromat cell with extensive use of damping wigglers. The key challenges of the lattice design are finding the balance between emittance minimisation and non-linear beam dynamics performance, and adapting the lattice to a collider-type tunnel geometry of the PETRA facility, with the long straight sections and low degree of superperiodicity. We present the lattice design and the beam physics aspects, focusing on the beam dynamics performance and optimisation, and the projected beam parameters taking collective effects and lattice imperfections into account.
