TI - Long-Term Orbit Stability in the PETRA III Storage Ring J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - The study of long-term orbit stability in the PETRA III light source plays an important role for the design of its upgrade to PETRA IV. The PETRA III tunnel is made of individual segments that move against each other. Here, the long-term drifts of the tunnel ground that are mostly introduced by temperature variations, are of the highest concern for the PETRA IV alignment tolerances and orbit stability. This paper studies the evolution of the beam orbit and corrector magnet currents over several years and correlates tunnel movement to RMS orbit drifts.
