The 26th LARP Hi Lumi collaboration meeting will be held in the Kavli Auditorium located just to the west of the recently constructed SLAC User Support Building that now dominates the main entrance to SLAC. The meeting will follow the traditional collaboration meeting format. There will be plenary presentations on Wednesday May 18, including talks by potential new Toohig Fellow finalist candidates. Parallel sessions are foreseen for Thursday May 19 and a final plenary session on Friday morning May 20. On the afternoon of May 20 interested parties will stay to discuss and develop a proposal for a continued LHC Accelerator Research program that would, if funded, be executed in parallel with the US LHC Hi Lumi Upgrade Project. A final agenda is now available. A no-host dinner has been organized for Wednesday evening. See the "Collaboration Dinner" link for more details. Please sign up for this dinner when you register.
