Description
Following the SPS crab cavity tests in 2025, dedicated machine studies were carried out to investigate optics perturbations introduced by the cavity module and their relation to resonance driving terms. Particular emphasis was placed on identifying possible sextupolar components and assessing their impact on the betatron tune. Measurements using controlled orbit bumps were performed to isolate the cavity’s contribution and to benchmark model predictions. The results provide valuable input for the interpretation of beam dynamics observations during the tests and for the refinement of the SPS optics model in view of future crab cavity operation.
