Title: NSLS-II Ground Vibration Stability Studies and Design Implementation

Abstract

We report that next-generation synchrotron accelerator facilities pushing the envelope of resolution to just a few nanometers and possibly atomic scale (~1 nm) require extreme stability of their experimental setting. Such stability is greatly influenced by the background micro-seismic activity and natural disturbance sources that are present throughout the globe and the cultural, man-made noise stemming from traffic on nearby highways and railways, operating machinery, and other activities. Defenses against such negatively impacting environment include smart conventional design of facilities, isolation of experiments, careful consideration of the selected site by providing ample distance from sources or protection by depth and, most importantly, qualification/quantification of the ground vibration environment both in terms of amplitude and spectral characteristics. Qualification and quantification of the site-specific noise environment may be utilized in the implementation of defense features in the design of the facility and high-sensitivity experiments. The performance is measured by the adherence to specific stability criteria that are ever-demanding, given the nature of the experiments that are sought where resolution down to a few nanometers is required. Furthermore, the selection of the optimal site and the quantification of the unavoidable background noise are important aspects to be considered in assessing the performance ofmore » such facilities.« less
