      Session 1: General Overview
      • 08:30
        Scenario for commissioning of the powering system 25m
        •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

        Powering Test Overview 30m
        •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
        Speaker: Boris Bellesia
        Slides
    • 09:55 → 11:30
      Session 2: Safety and access
      • 09:55
        First Outcomes of the Safety Task Force (the RULES) 20m
        •Tunnel access during powering – what areas can be accessed during powering as a function of current / energy in the different circuits? Clear and transparent rules •Matrix between powering and access (where not to go when?) •Document to be provided
        Speaker: Ralf Trant
        Slides

        COFFEE break 20m
      • 10:35
        How to ensure safety during powering? (ENFORCING the RULES) 30m
        •Powering phase I at low current: How to ensure that the current does not exceed the “safe” value? •Powering phase II: How can we be sure that nobody is in when we power? •Underground access during powering phase I and II for interventions: How to ensure that we do not power a circuit during such intervention (such as with the PIC)? •Underground access during commissioning of the powering system? Is it required? (EE switches, cut water, triplet…) •Hardware commissioning using the access system •Set the rules for access, different modes, transition from shutdown to commissioning/operation
        Speaker: Matteo SOLFAROLI
