Joint HL-LHC and LIU Brainstorming Session

Friday 24 Jun 2011, 08:00 → 14:00 Europe/Zurich

Le Hangar (Jiva Hill Park Hotel)

Mike Lamont (CERN)

This event is jointly organized by the HL-LHC and LIU projects to try and find solutions to the present discrepancy between the estimated needs of the LHC and the possibilities of the upgraded injectors. 
This event is a closed session, only invited participants may apply.  
This event will be followed by a lunch at the Jiva Hill Park Hotel.
If you wish to register for the lunch, please send a confirmation to andrey.nadine@cern.ch  before Friday 20 May.
