  3. Cabling campaign • Replace irradiated cables, avoid unnecessary cable length if possible, eliminate cable with PVC if possible • Cable campaign foreseen end 2013 for 4 months • Only signal and control cables (not DC cables) between patch RAL and Patch RX • 700 cables = 100 km in TCC2/TDC2 for the time being • End user to fill a DIC if additionnal request In discussion TCT: Top cable tray, AA: Almost All, R: Rest, Part: Partial.

  4. Air handling unit and cooling circuit • Leaking valve replacement foreseen in LS1 • North Area AHU consolidation planned for 2017 and cooling station for 2021 • AHU’s upgrade (add humidity control, make controls reliable) • Increase efficiency of air ventilation: at present the TDC2 tunnel is a dead-end and no clear air flow is set in the extremity toward TT20 (test in progress).

  5. List of activities for LS1: Magnet refurbishment • New cooling connection for all magnets • Global replacement of EPDM/Kevlar water hoses and gaskets in TDC2 / TCC2 • Y-shape fitting replacement by welded parts • Interlock: Thermometer and Manometer contacts get corroded, triggering inconsistent machine stops; • Insulation of cables is cracked in the patch panels, the magnet safety system could malfunction • Interlock systems will need consolidation in the future. A more modern system should be defined and implemented at the same time.

  6. Vacuum upgrade • Replace of damaged vacuum chambers and bellows • Replacement of ion pumps which are not or are poorly working at present. Change of ion pumps’ cables and connectors. • Increase of the number of pumps whenever possible and replacement of some ion pumps by new-generation NEG cartridges to accelerate recovery after air venting. • Beam line protection system in critical areas Courtesy of P. Chiggiato

  7. Lighting system and LV network • Lights upgrade (rad hard lights to be developed) • LV cabinet to be refurbished and moved away from targets and TAX areas

  8. Civil engineering • General infrastructure consolidation • Maintain drain network • Roof and floor cracks to be cured • Remove PVC hoses

  9. Beam line upgrade • Re-alignment of all secondarylines (neverdonesince installation mid seventies) • New PU-jacks for supportingbeamelements

  12. Use of TruView

  13. Beam monitors • A lot of beam monitors are corroded and must bechecked. • BE-BI linkpersonbeingdefined

  14. Organization: review by equipment or infrastructure

  15. Organization: review by areas
