  9. External Constraints Two non-MEG beam times in ’04/’05 + “Praktikum” Can turn on COBRA only on Wed. until fall ‘04 Beam Transport Solenoid and Separator not ready before ’05 Shutdown Internal Constraints “Exclusive” tasks: Drift Chamber – Timing Counter – Field Mapping – Beam Line Commissioning Schedule for different parts Combined Area Schedule Goal: Detector assembled before start of beam in 2006
