A Multi-Turn Measurement System for the CERN PS

Multi-turn beam position measurements on one or more pickups provide very important information needed to derive machine optics parameters. A variety of analyses is possible, such as determination of phase advance, detuning with amplitude, and most important, the exploration of phase space. In this paper we present a new multi-turn acquisition system for the CERN Proton Synchrotron based on a CompactPCI fast digitiser and a new general object-oriented visualisation and analysis tool for the acquired multi-turn data.
