Linear Optics Measurements in the ESRF Booster

A series of experiments was conducted in the ESRF booster in order to measure its linear optics. A steerer response matrix was developed and used to optimise the orbit correction at injection by producing a refined model. This matrix was also used to measure the beta functions along the accelerating cycle and the steerer calibration. Dispersion was measured with classical RF scans and compared to the model. Finally, chromaticity measurements were performed for different sextupole settings enabling their calibration and optimisation.
