TL;DR: In this paper, equilibrium and nonlinear beam dynamics parameters determining decoherence patterns in Turn-by-Turn (TbT) position data are estimated and compared with corresponding values of the nominal storage ring model.
Abstract: A considerable amount of beam information is conveyed by Turn-by-Turn (TbT) data of Beam Position Monitors (BPM). In this work such data sets are analyzed for Sirius, the Brazilian 4th Generation 3 GeV synchrotron light source. In particular, equilibrium and nonlinear beam dynamics parameters determining decoherence patterns in TbT position data are estimated and compared with corresponding values of the nominal storage ring model.

TL;DR: In this article, the authors explored various data acquisition techniques at different squeezing steps during commissioning and compared to results obtained from closed orbit distortion, which could enable fast optics measurements for rapid identification of unexpected error sources.
Abstract: SuperKEKB, an asymmetric electron-positron collider, has recently achieved the world record instantaneous luminosity of 2.8 × 1034 cm-2s using crab-waist collision scheme. In order to reach the design value of 6 × 1035 cm-2s a vertical beta function at the interaction point of 0.3 mm is required, demanding unprecedented optics control. Turn-byturn beam position data could enable fast optics measurements for rapid identification of unexpected error sources. Experiments exploring various data acquisition techniques at different squeezing steps during commissioning are presented and compared to results obtained from closed orbit distortion.
