This homepage is a compilation of ground motion measurements which have taken place since 2002, not only in DESY but in many high energy and synchrotron radiation laboratories around the world. This database of ground motion data is therefore a very first of its kind.

Since 2006, we have expanded our vibration studies program and have concentrated our efforts on vibration study of accelerator components, in particular, quadrupoles in both room and superconducting temperatures, in accelerating modules. This study is aimed for both the European Xray Free Electron Laser (XFEL) and the International Linear Collider (ILC).

Our data, both ground motion in various sites and vibration studies of accelerating modules, is available for download. Please contact us if you have any questions.
