LS1 EN-EL activities Power distribution and Operation
7 LS1 Day - François Duval EN-EL
Replacement of SILCON UPSs
All cryo and machine : 82 UPS
Any new UPS connections Requests must be done before end of June 2012
12 Juin 2012
UPS machine : 2 UPS in RE (x16)2 UPS in UA (x8)2 UPS each LHC point (US, UW ou UJ) (x8)
UPS cryo :2 UPS on LHC even points (US, UW) (x4)2 UPS on surface even points (SA, SH) (x4)2 UPS in PM18
8 LS1 Day - François Duval EN-EL
Replacement of SILCON UPSs
Impact on other activities: 6 weeks per area (for 2 UPS)
Distribution downstream off during works
Possible refeeding from diesel network (subject to request justified by safety)
Transport and handling: ~ 660 kg for an UPS and 2000 kg for battery sets (removal of old ones as well ) Lifts on Points 3, 5 et 7 too small for UPS : Width > 800 mm
Alcoves RE : A safety issue has to be considered: Charging batteries may lead to hydrogen production. Ventilation must be dimensioned so that the risk of explosion is eliminated (EN/EL, GS/ASE, HSE)

Cables & Fibres
Additional resources AGH (12 project associates from Krakow) Fellows & associates (+10 in 2011/2012) 2 installation contracts (doubled manpower) FSU being prepared Specialists + project managers required (skilled
and experienced people)

33 LS1 Day - François Duval EN-EL
Cables & Fibres
Help from other departments & experiments
We still want new people working with EL team in order to have coherent works done
Work supervisors Knowledge and experience of cable laying or fibre blowing technologies Experience in work site supervision Knowledge of site works
Project managers Project management People management Schedule & Budget management Knowledge of dedicated softwares(GESMAR, Câblothèque)
12 Juin 2012

Cables & Fibres
But there are limits to the increase of manpower:
Lack of experience Increase of manpower of contractors CERN access, hotels, logistics bottle neck, Base vie? Schedule/coactivity
12 Juin 2012
35 LS1 Day - François Duval EN-EL
LS1 will be a very huge shutdown also for EN/EL
On the HV & LV infrastructure side, The program will be done with some additional resources
On the cables & fibres side, the situation is critical: prioritization is done but the effort is huge for the section in charge. Additional resources have been deployed from other departments: more are needed.
We are worried about the flow of requests which are still popping up in PLAN@CERN or elsewhere
