Crossing Angle Anti-Leveling at the LHC in 2017
In 2017, LHC incorporated in operation an anti-leveling procedure of adapting the crossing angle of the colliding beams in steps to increase the integrated luminosity. In this paper, we present the Dynamic Aperture simulations that were employed to identify the operational margins, and therefore def...

| Sumario: | In 2017, LHC incorporated in operation an anti-leveling procedure of adapting the crossing angle of the colliding beams in steps to increase the integrated luminosity. In this paper, we present the Dynamic Aperture simulations that were employed to identify the operational margins, and therefore define the leveling steps. The results are complemented by observations from nominal operation as well as projections for the 2018 run. Additional anti-leveling techniques, investigated in dedicated machine studies are also discussed |
