Measurement of linear/non-linear lattice
We review the basic concepts of beam dynamics in ultra low emittance rings including single particle and collective effects. Some emphasis is given to correct implementation of the optics, with the relevant operational issues and diagnostics requirements.
Different approaches to infer magnet and optics parameters from beam-based measurements at the ESRF storage ring are reviewed. Main results and limits of the established techniques are examined. Possible improvements or alternatives are proposed and discussed in the light of first experimental results. A report on accuracy studies of linear optics measurements, based on both turn-by-turn and...
The 10kHz fast acquisition BPMs together with an AC excitation of the corrector magnets allow to speed up the beam based alignment process at ALBA. The former approach relies on software synchronization and tango device servers to execute a series of DC corrector magnets and quadrupoles settings designed to avoid the quadrupole hysteresis effects. The approach that we present here is simpler,...
