Beam-beam effects long-range and head-on
The 2015 LHC run has shown the beauty of having weaker beam-beam effects with respect to 2012 physics run. The 2015 setup has been defined to allow Landau octupole and chromaticity to be powered at maximum currents to fight coherent instabilities. Quantitative studies of the impact of reduced crossi...

Sumario: | The 2015 LHC run has shown the beauty of having weaker beam-beam effects with
respect to 2012 physics run. The 2015 setup has been defined to allow Landau
octupole and chromaticity to be powered at maximum currents to fight coherent
instabilities. Quantitative studies of the impact of reduced crossing angles on
the beam and luminosity lifetimes have been used to compare to expectations from
Dynamical Aperture studies. Possible scenarios for the 2016 RUN will be
presented highlighting the beam-beam limits expected from long range and head-
on. |
