  1. Prioritization of Cabling Needs P. Bonnalwith inputs from J.-C. Guillaume, P. Lelong and D. Ricci P.BonnalLIU-PSB meeting 2012-01-12

  2. Prioritization of Cabling Needs • IEFCMeeting held on Friday 16th December: • Critical cable areas in SPS and PS complex (D. Ricci) • “difficulty / impossibility to add new cables” • The issue: • New cables to be pulled • Using existing routes • Through new routes (PSB area ↔ MPSB) • Already unused cables to be removed • Future unused cables to be removed • Crowded cables areas

  3. A few pictures (Wed. 21st December)

  4. Prioritization of Cabling Needs → ideas • Prelim. discussion with J.-C. Guillaume, P. Lelongand D. Ricci : • Possible strategies: • Removing all cables then (re)pulling all cables → LHC • Removing some cables, pulling new cables… repeating • Removing all unused cables in one campaign LS1then pulling all new and reused cables in LS1 • Removing all unused cables in one campaignthen pulling all cables in LS1 and SD 14-15 • Removing all unused cables in one campaignthen pulling all cables in LS1, SD 14-15 and SD 15-16 • …

  5. Prioritization of Cabling Needs → ideas • Prelim. discussion with J.-C. Guillaume, P. Lelongand D. Ricci : • Issue #1 → Existing databases: • Before 1989 : paper listings ; routing unknown • After 1989 : in EL Cablothèque • Issue #2 → Cable marking • Issue #3 → Cables to remove • Issue #4 → Cables to pull • Issue #5 → Work optimization (remove then re-pull) • Issue #6 → Possible civil works required • Issue #7 → EN-EL workload (already 8 projects on-going)

  6. Prioritization of Cabling Needs → ideas • Prelim. discussion with J.-C. Guillaume, P. Lelongand D. Ricci : • Strategy to be set-up → PSBU meeting → end of February ? • In favor of a single cable removal campaign → LS1 ? • Possible schedule:

  7. Preparatory works • Identifying all new vs. old equipment ☞ on-going and associated cabling requirement ☞ schematic layout required ☞ to initiate soon • Identifying cables that are/will be useless • Identifying new cables that need to be pulled • Identifying rather crowded cables areas • Optimizing cable routes • Marking then removing these useless cables • Re-pulling useful removed cables + pulling of new cables
