Performance of the collimation system during 2016 - hardware perspective

The commissioning experience of the LHC collimation system in 2016 is reviewed together with the hardware performance. Despite of the limited changes in hardware and software, the time spent in commissioning, set—up and qualification activities has been reduced thanks to system upgrades like the dep...

description The commissioning experience of the LHC collimation system in 2016 is reviewed together with the hardware performance. Despite of the limited changes in hardware and software, the time spent in commissioning, set—up and qualification activities has been reduced thanks to system upgrades like the deployment of 100 Hz BLM logging for collimator alignment and detailed commissioning of embedded BPMs. In particular, the reliability and stability shown by embedded BPMs allowed to systematically align TCT collimators and accommodate beam manipulations at the IPs; furthermore, following the gained experience, a proposal of SIS interlock based on the readout of embedded BPMs is made. The LHC collimation system experienced a limited number of faults, which is reported. Hardware changes foreseen for EYETS 2016, mainly dedicated to MD activities. are outlined.
