Metodologia aplicada ao monitoramento e análise de vibrações do piso em áreas críticas das linhas de luz do Sirius

Abstract

Mechanical vibrations are present in many everyday situations, and understanding this phenomenon is fundamental to the study of physical and engineering systems. Vibrations can be defined as oscillatory movements of a mechanical system around a point of equilibrium, and can have different origins, directions, and intensities, which can generate significant consequences for the performance and stability of sensitive equipment. At the Sirius electron accelerator, where research spanning micrometer and nanometer scales is conducted, the precision and stability of the beam at each light line are essential. Any interference, even of small magnitude, can compromise the quality of measurements and experimental analyses. In order to understand and monitor these interferences, a methodology was developed for measuring and analyzing vibrations in the storage ring floors, the experimental hall, special floors, and granite tables of Sirius. The results showed that the ring floor exhibits adequate stability and homogeneity, even in the face of external interference, and that there is efficient decoupling between the ring floor and the experimental hall. Furthermore, it was observed that the granite tables are more sensitive to low frequencies, reinforcing the importance of continuous monitoring.
