- Chiara Bracco (CERN)
08:45 - 09:10
Room: 774/R-013 a) Existing design: kickers, protection elements, controls logic, BETS, considered failures and failure rates etc. b) Operation during past runs: reliability, new failures (impact on beam and protection elements) and mitigations applied up to now (generator cleaning, radiation shielding). c) Possible limitations for Run III. d) New requests (additional kickers or separate vacuum tanks) and expected performance.

09:15 - 09:35
Room: 774/R-013 a) Actions foreseen during LS2 and present status (switch consolidation, grounding) b) additional MKBs or other solutions to be investigated (separate vacuum tank) with technical details. When possible applying first mitigations? Latest date to start production.

09:40 - 10:00
Room: 774/R-013 a) Upgrade foreseen during LS2 (MKB re-triggering, IPOC upgrade, sparking surveillance, etc.) b) Actions foreseen for LS3 (what is in the baseline: Triggering synchronization distribution, powering etc.) c) What is not in the baseline and might be needed (replacement of aging equipment, etc. consolidation? Operational budget?)
