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
