Measurement of Linear Lattice Functions in the ESRF Storage Ring Using Turn-By-Turn Data

Model-independent methods to measure linear optics functions have been tested in turn-by-turn data from the ESRF storage ring. The methods do not necessitate neither the knowledge of the model nor magnetic element manipulation. They use only the positions measured in consecutive BPM of betatron oscillations issued by small transverse kicks. The phase advances and tunes necessary to construct the transfer matrices are issued by refined Fourier analysis. Measurements of off-momentum optics parameters using longitudinal beam excitation are also presented.
