Description
This work evaluates the effects of the first vertical polarization undulators (VPUs) installed in the SIRIUS storage ring on electron-beam dynamics. These insertion devices (IDs) are light sources for the CARNAÚBA and CATERETÊ beamlines at the Brazilian Synchrotron Light Laboratory (LNLS). The analysis combines numerical simulations and beam-based measurements to quantify static and dynamic orbit distortions, optics perturbations (beta-beating and tune shifts), effects on injection efficiency, and changes in equilibrium beam parameters, including beam lifetime. The effectiveness of ID feed-forward compensation in mitigating these effects is assessed. Results characterize the operational impact of the VPUs on storage ring performance, providing safe conditions for beamline operation.
