25. LBDS Performance (20' + 10')

Chiara Bracco (CERN)

31/01/2019, 10:30

• Reliability of the system/lessons learnt during Run 2 and from re-commissioning after LS1
• What are the main evolutions of the system during Run 2? What were the main limitations encountered and which limitations will remain for Run 3?
• What are the main changes foreseen and how will they impact machine operation?
• Can we reach 1.8E11 ppb in 1.8 um? If not, what mitigation measure is...

26. LHC Dump Assembly – Operational Feedback and Future Prospective (15' + 10')

Antonio Perillo Marcone (CERN)

31/01/2019, 11:00

• What are the main evolutions of the system during Run 2? - What were the main limitations encountered and which limitations will remain for Run 3?
• What are the main changes foreseen and how will they impact machine operation?
• Can we reach 1.8E11 ppb in 1.8 um? If not, what mitigation measure is needed?

27. Power Converters and their control (20' + 10')

Slawosz Uznanski (CERN)

31/01/2019, 11:25

• Evolution of power converter and their control during run 2
• FGC-lite feedback on experience and plans for LS2

29. Collimation (20' + 10')

Nuria Fuster Martinez (CERN)

31/01/2019, 14:00

• Performance and evolution of the system
• Collimation controls: alignments and settings, BPMs
• Decreasing setting up time and can OP play a bigger role in setting up?
• Loss maps: what did we improve and can we improve further?
• Operational aspects
• Crystals collimation: contact EN-STI for input

30. ADT and ObsBox (20' + 10')

Martin Soderen (CERN)

31/01/2019, 14:30

• Evolution during the Run
• Is noise an issue and can we do better?
• Feedback from the users?
• What changes are foreseen?

31. Machine Protection System (20' + 10')

Daniel Wollmann (CERN)

31/01/2019, 15:00

• Have we been running the machine always safely during run 2 (normal & MD running)?
• Intensity ramp-ups: evolution during the run, issues found and time required
• Main failure cases encountered
• Experience with software/hardware interlocks
