      abstract     = {The tunnel of the synchrotron light source PETRA III is
                      build from separate segments that are joint together every
                      24 m. The normal conducting magnets heat up the tunnel when
                      operating, which leads to an expansion of the concrete walls
                      and floor introducing movements between the tunnels
                      segments. Especially during warm-up periods after shutdowns,
                      this results in a drift of the accelerator elements that is
                      transferred on the circulating beam over a duration of days,
                      weeks or months according to the length of the cool-down
                      period. This paper shows that not only inside temperature
                      effects but also seasonal temperature changes are relevant.},
