PHASE-SPACEDYNAMIC TRACKING BY A TWO PICKUPSDATA ACQUISITIONSYSTEM
A. Drago, S. Guiducci, C. Milardi · 2005
A twopickups dynamictracking dataacquisition system hasbeendeveloped atLNFfortheDA NE Phi- factory. Twooscilloscopes sample horizontal andvertical sum and difference signals fromtwo pickups simultaneously; thesampling clockislocked tothe DA NE timing system. A horizontal kickexcites the beammotion andinitiates theacquisition. Turn-by-tum signals areconverted tobeamposition andstored ona server inadatabase using timestamp labels. Oscillation amplitude versustime,phasespacedistribution and frequency domainanalysis havebeenevaluated for several lattices anddifferent settings ofsextupoles and octupoles. Results areusedtochecktheDA NE non- linear model.
