FCC Infrastructure & Operation studies: objectives, work program, organization
Ph. Lebrun & P. Collier
1st FCC Infrastructure & Operation meeting
CERN, 22 January 2014

2. European Strategy Update on Particle Physics Design studies and R&D at the energy frontier
“CERN should undertake design studies for accelerator projects in a global context,
with emphasis on proton-proton and electron-positron high-energy frontier machines. These design studies should be coupled to a vigorous accelerator R&D programme, including high-field magnets and high-gradient accelerating structures, in collaboration with national institutes, laboratories and universities worldwide”
