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 concernfor the PETRA IV alignment tolerances and orbit stability. This paper studies the evolution of the beam orbit and corrector magnet currents over several years in order to identify locations of misalignment in relation to the mechanical movement between tunnel segments.
