Description
The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN is set to introduce a series
of major upgrades across the LHC complex, including the implementation of crab cavities,
applied for the first time in a hadron machine. These cavities are designed to increase beam
luminosity by compensating for the geometric luminosity reduction caused by the crossing
angle at the interaction points.
However, the crab cavity controller and RF power stage introduce additional phase noise into
the system, which can lead to beam emittance growth if not properly mitigated. A new
solution, known as the beam noise feedback system, is therefore being developed to suppress
the impact of this noise.
This presentation will outline the main challenges of the project and introduce the mitigation strategy based on AMD RFSoC technology as well as some preliminary results obtained from the Super Proton Synchrotron.
