@cern.official: This #PhotoOfTheWeek features the 16th #HiLumiLHC collaboration meeting, which took place earlier this month. The #HiLumiLHC is a major upgrade to dramatically improve the performance of the LHC, CERN’s largest accelerator. Over 1.2 kilometres of the LHC are being dismantled and replaced by new systems to increase the luminosity (the number of particle collisions). A total of 170 people from CERN and the project's worldwide collaborating institutes came together at Royal Holloway, University of London, for the collaboration meeting to review progress and discuss upcoming milestones as the project moves into large-scale deployment.
