improvements• LHCb: consolidations

•Machine: Collimation & prepare for crab cavities & RF cryo system•ATLAS: new pixel detect. - detect. for

ultimate luminosity.•ALICE - Inner vertex system upgrade•CMS - New Pixel. New HCAL

Photodetectors. Completion of FWD muons upgrade•LHCb - full trigger upgrade, new vertex

detector etc.

EN LS1 - Goal

Feb. 8th 2012

Take all measures for a safe and reliable operation of LHC @ 7TeV/beam

Full maintenance Consolidation & upgrade

LHC machine & experimentsInjectors


EN LS1 - Time window

Feb. 8th 2012

• 20 months from Beam OFF to Beam ON– Actual total duration agreed between experiments and

machine• LHC machine: 20 months• ALICE: 12 months (up to 15 months)• ATLAS: 15 months (but from April 2013)• CMS: 20 months• LHCb: 12 months

Marzio: “ LHC experiments upgrade & maintenance”


EN Requests Approval

Feb. 8th 2012

• Meetings being held with stakeholders to understand Goal of activities Time key drivers Support needed

• For accelerator complex: database of requests is being filled : LHC and injectors

To detect conflicts/overloads & to decide what is compulsory, what we can afford &what we have to postpone to LS2

Priorities set for LHC machine– P1: Beam to 6.5-7TeV, nominal performance– P2: Reliable operation– P3: CERN approved projects– P4: no CERN approved projects

• Mauro : “EN-CV upgrade & consolidation”• Francois: “EN-EL upgrade & consolidation”• Erk : “RF upgrade program in LHC injectors

and LHC machine“

Additional activities, especially those requiring supports from other groups can disorganize the global schedule, and induce delays.

CSCM tests in all sectors will cost around 4 weeks


EN Outline

Feb. 8th 2012

• General frame

• Injectors


• Organization

• Conclusion


EN Organization

Feb. 8th 2012

• Schedule & logistics– Lots’of work still to be done in matter of schedule &

logistics for all the other activities w.r.t. skeleton schedule

• Preparation– ECR have to be written prior to works– Modification of the envelope of your equipment ICL– DIMR– Materials have to be ready in due time…..This has often induced

delays !!!

• Follow-up– Weekly coordination and scheduling meeting

Reiner : “QPS upgrade and machine protection during LS1 ” Miguel : “Vacuum upgrade”Laurent: “Cryogenics system: strategy to achieve nominal performance and reliable operation “


EN Conclusions

Feb. 8th 2012

• Analysis of requests well advanced (LHC & experiments, injectors)

– w.r.t. priorities & resources & time & interaction between groups– New requests will be scrutinized, especially the support form

overloaded groups (VSC, EL, CV)

• “Skeleton” schedules for LHC machine & injectors ready

• Workload is huge and the schedule is tight

• Worksites have to be well prepared.Please do not forget layout, integration & safety
