The complexity of operation will be extreme: very critical technical subsystems large parameter space need for online magnetic and beam measurements real time feedback loops.
Some 500 objects are capable of moving into the aperture of either the LHC Ring, or the transfer lines, ranging from passive valves up to very complex experimental detectors

of damaged equipment would take long, for example, the exchange of a superconducting magnet takes about 30 days

SummarySummary
We have addressed the LHC challenges and appropriate solutions have been deployed
The LHC infrastructure has been tested almost completely on previous milestones (LEIR, TI2/8 Transfer Lines, CNGS, SPS, LHC HWC) we are confident that we can meet the LHC challenges
Part of the enormous human resource effort invested for LHC comes from international collaborations Their contribution is highly appreciated Looking forward to more fruitful collaborations
We have scheduled our efforts for the 450 GeV engineering run in November 2007 We are now ready and eager to see beam in the LHC
