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

Follow Up From Previous Meetings (2019)

Origin Follow-up Status
18 - January - 2019
PSB Beam Commissioning Review HW and beam commissioning schedules in context of equipment experts availability  
Consider making commissioning EDMS documents in all injectors as in the PSB  
Prepare beam availability schedule for each experimental facility  


Mandate (2018): Link to indico page

  • Ensure readiness of plans/procedures/tools and establish teams for commissioning of the injectors afterLS2
  • Organise, execute, analyse beam commissioning from post-LS2 to LS3 (i.e. during Run3), which implies
    • Recover pre-LS2 performance
    • Commission LIU beams to full performance by end of Run3
    • Establish beam milestones roadmap to meet the above two targets
