Joint LIU / HL-LHC meeting
→
Europe/Zurich
865/1-D17 (CERN)
Description
Aim:
- to discuss ‘LIU / HL-LHC’ interface subjects
- to discuss possible improvements (strategies, equipment improvements, schedule, beam parameters) beneficial for both projects
- to clarify misunderstanding and identify parameter mismatch
- to update parameter tables if needed
- to ensure coherency of timeline and decisions between the two projects (e.g. ions)
