  Session 1 - HWC experience & future plans
  - 08:30
    
    Strategy 30m
    
    - Achieve circulating beam as soon as we have a cold and minimally commissioned machine. - Commission with beam to demonstrate that the machine is viable (captured beam and 1 hour lifetime). - The first run for physics. - The fall back solution: - One or more sectors require a major repair and have to be warmed up. - Sector test from one side or both on several healthy sectors while the repair is ongoing – access ? Or time sharing the week. - The energy strategy. - Schedule
