Strategy for Landau damping of head-tail instabilities at top energy in the HL-LHC

The main aspects linked to Landau damping of head-tail instabilities at top energy in the HL-LHC are discussed, in particular the interplay between the arc octupoles and long-range, offset or head-on beam-beam interactions as well as lattice imperfections. When possible, the models are compared wi...

Sumario:The main aspects linked to Landau damping of head-tail instabilities at top energy in the HL-LHC are discussed, in particular the interplay between the arc octupoles and long-range, offset or head-on beam-beam interactions as well as lattice imperfections. When possible, the models are compared with the operational experience of Runs 1 and 2 of the LHC. Based on these considerations, various operational scenarios are discussed identifying their strengths and limitations.
