| Abstract | In the context of the HL-LHC upgrade, RF Crab Cavities (CCs) are one of the key components to achieve the target integrated luminosity. Due to the increased bunch intensity, the collider will operate with a large crossing angle scheme to alleviate the long-range beam-beam effect. The CCs will counteract the geometrical luminosity reduction factor coming from the large crossing angle. Amplitude and phase noise injected from the CC low-level RF control are known to induce transverse bunch emittance growth. This contribution presents measurements of emittance growth induced by amplitude noise, performed in the CERN Super Proton Synchotron (SPS). The measured emittance growth was found to be dependent on the amplitude detuning induced by the SPS octupoles, although no dependence was predicted by the available theories and models. In this paper, the measurement results will be presented and compared with tracking simulations. |
