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.}, month = {Jun}, date = {2022-06-12}, organization = {13th International Particle Accelerator Conference, Bangkok (Thailand), 12 Jun 2022 - 17 Jun 2022}, keywords = {Accelerator Physics (Other) / MC2: Photon Sources and Electron Accelerators (Other)}, cin = {MPY / MPE / MSK / MBB}, cid = {I:(DE-H253)MPY-20120731 / I:(DE-H253)MPE-20120731 / I:(DE-H253)MSK-20120731 / I:(DE-H253)MBB-20120731}, pnm = {621 - Accelerator Research and Development (POF4-621) / 6G3 - PETRA III (DESY) (POF4-6G3)}, pid = {G:(DE-HGF)POF4-621 / G:(DE-HGF)POF4-6G3}, experiment = {EXP:(DE-H253)PETRAIII(machine)-20150101 / EXP:(DE-H253)PETRAIV-20220101}, typ = {PUB:(DE-HGF)8 / PUB:(DE-HGF)7}, doi = {10.18429/JACOW-IPAC2022-THPOST001}, url = {https://bib-pubdb1.desy.de/record/479135}, }
