7. Overview: LHC availability and outlook

Andrea Apollonio

13/12/2016, 14:00

The LHC exhibited unprecedented availability during the 2016 proton run, producing more than 40 fb-1 of integrated luminosity, significantly above the original target of 25 fb-1. This was achieved while running steadily with a peak luminosity above the design target of 1e34 cm-2s-1. Individual system performance and an increased experience with the machine were fundamental to achieve these...

9. Technical Services: Unavailability Root Causes, Strategy and Limitations

• Split the TI events leading to unavailability into the relevant systems / sub-systems
• Breakdown the downtime with respect to each, analysing with respect as TIOC sees fit.
• Identifying the measures that are put in place with respect to these.
• Identifying the measures & mitigations that could be foreseen for 2017
• Making observations versus 2015

11. Injectors: Unavailability By Machine, Root Causes, Strategy and Limitations

Bettina Mikulec

• Split the injector events leading to unavailability into the relevant systems / sub-systems
• Breakdown the downtime with respect to each, analysing with respect to the injector machines.
• Identifying the measures that are put in place with respect to these.
• Identifying the measures & mitigations that could be foreseen for 2017
• Making observations versus 2015

10. Cryogenics: Unavailability Root Causes, Strategy and Limitations

Krzysztof Brodzinski

• Split the cryogenic events leading to unavailability into the relevant systems / sub-systems
• Breakdown the downtime with respect to each.
• Identifying the measures that are put in place.
• Identifying the measures & mitigations that could be foreseen for 2017
• Making observations versus 2015

8. Recurring Sources of Premature Dumps

• Analysing the beam aborts from 2016
• Breakdown the beam aborts into root causes.
• Expand each root cause and make observations vis-a-vis their impact on operations.
• Identifying the measures & mitigations that could be foreseen for such abort causes in 2017
• Making observations versus 2015.
