LIU Beam Commissioning Coordination Working Group

co-chaired by G. Rumolo (BE/ABP) and V. Kain (BE/OP)

Mandate: 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

2018 Goals See following link (2018-BCWG.pptx: 2018-BCWG.pptx)

Previous meetings https://indico.cern.ch/category/9633/
  Super settings for generation and trim (Delphine)  
  LINAC4 responsibilities: what is happening during LS2?  
  New timing system approach: where shall/should we go  
  Reference measurements end of 2018 for after LS2. How to store reference measurements? New framework?
