Description
In the High-Luminosity LHC (HL-LHC) era, increased beam intensities and brightness impose stringent requirements on the beam-coupling impedance of accelerator components. This contribution summarizes recent studies on impedance mitigation for several new devices to be installed in the framework of the HL-LHC upgrades, illustrating design optimizations based on results from multiple electromagnetic simulation solvers and RF measurements. Examples include the optimized design for crab cavity pick-ups, linear beam wire scanners, and beam gas ionization monitors. These developments contribute to a consistent impedance mitigation strategy that reduces beam-induced heating at high intensities, maintaining device functionality and beam stability in the HL-LHC era.
