Performance of the LHC collimation system during 2015
During the long shutdown, a total of 32 collimators were replaced or installed to improve the Run 1 system, including 18 new collimators with embedded beam position monitors , additional physics debris collimators, additional passive absorbers and the re-installation or displacement of existing coll...

| description | During the long shutdown, a total of 32 collimators were replaced or installed
to improve the Run 1 system, including 18 new collimators with embedded beam
position monitors , additional physics debris collimators, additional passive
absorbers and the re-installation or displacement of existing collimators. The
commissioning experience as well as the performance of the collimation system in
2015 is reviewed following these upgrades. In particular, the operational
experience with the embedded BPM collimators is discussed, emphasizing the
improvements on alignment efficiency and the strategy for better orbit
monitoring. Improvements of collimation setting validation through an optimized
loss map strategy are also presented. Further improvements planned for 2016 are
discussed. |
