Mandate (2019): Link to presentation

• Ensure readiness of plans/procedures for commissioning preparation and commissioning
• Ensure readiness of tools
• Establish teams
• Organize and analyze beam commissioning

  • The LIU-CCC mandate will be reviewed (in the course of 2021, pending commissioning progress) and remaining activities will be merged into a new body together with other on-going activities (e.g. beam dynamics) to ensure the overall approved Beams Performance milestones.
• The LIU-CCC will report directly to the LIU project and when required the IEFC/LMC
• Identify required checks/commissioning activities for old and LIU equipment across the injectors
• Review the tools/applications/simulations/monitoring/pre-HW checks/CO required for the commissioning phase, identify outstanding/missing items and fix delivery deadlines, and follow-up progress
• Establish the detailed commissioning time line for LHC and FT beams
  • Define the LHC beam parameters to be reached throughout the injectors chain as a function of time for: LHCINDIV, LHC run2, each LIU commissioning step, LIU
• Ensure definition of neccesary LS2 dry runs and HWC, including planning of tests with EN/ACE
• Establish a draft time line for the the beam commissioning to the final LIU beam performance
