Phase Sub-phase Beam dump BLMs Beam Interlock Collimators TDI
Phase 1 & 2 Commission Injection region, establish circulating beam       OUT IN - CLOSED
Phase 3 - PILOT Establish circulating beam    Commission acquisition - no dump Injection inhibit OUT OUT
Phase 3 - PILOT Stable beam 450 GeV Commission dump at 450 GeV Dedicated commissioning period Beam based Interlocks: System by system verification First bootstapping attempt, subset to say 10 sigma nominal to provide some protection in ramp First attempt to position with respect to circulating beam
Phase 4 - Single bunch - intermediate intensity Stable beam 450 GeV Verify Continued commissioning   Preliminary commissioning to nominal injection settings Preliminary commissioning to nominal injection settings
Phase 6 - switch to nominal cycle Stable beam 450 GeV       Confirm Confirm
Phase 7 - PILOT Ramp pilot - snapback   Acquisition - no dump, check losses against thresholds   Coarse settings Out
Phase 8 - PILOT Ramp pilot - single beam, intermediate energies Commission dump at intermediate energies Limited sub-set to BIC following commissioning of dump Sub-set BLMs Coarse settings  
Phase 8: Single bunch - intermediate intensity Before going above in ramp ~2 TeV Verify     Nomainal Injection settings  
Phase 4: Multi bunch - pilot intensity - various configurations. Single beams leading to two beams Stable beam 450 Gev Check timing, injection vetos, abort gap Starts to get serious, tighten thresholds for critical BLMs, introduce thresholds for others. Start tuning. Critical BLMs, dump BPMs Progressively finer adjustment, orbit stabilisation First attempts at nominal positions during injection process
Phase 8: Single bunch - intermediate intensity Ramp Some stops in ramp, orbit stability As above As above Injection settings for ramp, orbit stabilisation is required n/a
  Ramp pilot - two beams          
  7 Tev - two beams          
  Collide pilot - unsqueezed          
  First atempts at squeeze [following  at least some of the stages shown below]          
Multi bunch - intermediate settings Injection Fully operational at all stages Passing damage threshold. All critical BLMs with appropriate thresholds Fully commissioned. BLMs, BPMS, etc. Fine adjustment Fine adjustment
