•
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

• Injectors
• LHC machine : Main activities and risks
• Organization
• Conclusion
Feb. 8th 2012

Organization
• Schedule & logistics
– Lots’of work still to be done in matter of schedule &
logistics for all the other activities w.r.t. skeleton
Reiner : “QPS upgrade and machine
schedule
protection during LS1 ”
Miguel : “Vacuum upgrade”
Laurent: “Cryogenics system: strategy
to achieve nominal performance and
reliable operation “
• 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
Feb. 8th 2012
K. Foraz - LHC Performance Workshop 2012
25
EN
Conclusions
• 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
