Botta, S. JACoW Publishing Geneva, Switzerland One of the most challenging problems for experimental setups at third-generation and especially fourth-generation synchrotrons are vibrations. In order to keep vibrations on a as low as possible level one must not only take extremely care in the design of all components but also have a profound knowledge of the sources of vibrations. We started a project to map the vibrations at PETRA III both locally and timely in order to get a better understanding of the influencing factors and possible consequences for the ongoing PETRA IV project. In this contribution we will report on our first results of this project.
