SPS and LHC Batch Spacing Optimisation

In 2016, part of the luminosity performance improvement for the ion run could be achieved by reducing the PS batch spacing in the SPS. The same optimisation process was then applied to proton beams resulting in the reduction of both SPS and LHC batch spacing in 2017 operation, i.e. to 200 and 800 ns...

description In 2016, part of the luminosity performance improvement for the ion run could be achieved by reducing the PS batch spacing in the SPS. The same optimisation process was then applied to proton beams resulting in the reduction of both SPS and LHC batch spacing in 2017 operation, i.e. to 200 and 800 ns respectively. In this contribution, the operation with and evolution of the new injection settings over 2017 is presented, together with the stability of rise-time of the individual switches for the two kicker systems. The luminosity gain following these changes is also evaluated and the expected luminosity for potential beam filling patterns in 2018 is investigated. Finally, the possibility for further improvements is discussed.
