CERN PS Optical Properties Measured with Turn-by-turn Orbit Data

The performance of the CERN Proton Synchrotron (PS) has been constantly increasing over the years both in terms of beam parameters (intensity and brightness) and beam manipulations (transverse and longitudinal splitting). This implies a very good knowledgeof the linear and non-linear model of the ring. In this paper we report on a detailed campaign of beam measurementsbased on turn-by-turnorbit data aimed at measuring the optics in several conditions as well as the resonance driving terms.
