•Scenarios: commissioning to 450 GeV and 4…5 TeV, high currents only to 4TeV initially •How to decide to go to 5 TeV? •What about circuits with “small” current? 4 TeV- 5 TeV? •Key dates in preparation and outlook to planning •LHC operation during the winter 2009/10

•Organisation of hardware commissioning, meetings, … •What happens before powering tests after cooldown •Commissioning of Warm sectors, Cold sectors and sector 34: what needs to be done? What can be dropped? •When should we work: 2 shifts during 5 days versus 3 shifts during 7 days, MPP analysis, what can be done in a nightshift – WE? Bottlenecks in manpower •Rules for patrols during powering tests
