LIU Commissioning Coordination Committee

co-chaired by G. Rumolo (BE/ABP), V. Kain (BE/OP), A. Huschauer (BE/ABP)

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
  • LIU beam commissioning objectives from post LS2 until end of 2021:
    • Recover the pre-LS2 LHC beam type parameters, including beams required for LIU setting-up (and/or according to schedule): LIU intensity PSB, PS.
    • 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
