Prioritization of Cabling Needs

P. Bonnalwith inputs from J.-C. Guillaume, P. Lelong and D. Ricci

P.BonnalLIU-PSB meeting 2012-01-12

prioritization of cabling needs1
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
prioritization of cabling needs ideas
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

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)

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:
preparatory works
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
