6. FCC-hh Luminosity Goals
Two parameter sets for two operation phases:
Phase 1 (baseline): 5 x 1034 cm-2s-1 (peak), 250 fb-1/year (averaged)
 2500 fb-1 within 10 years (~HL LHC total luminosity)
Phase 2 (ultimate): ~2.5 x 1035 cm-2s-1 (peak), 1000 fb-1/year (averaged)
 15,000 fb-1 within 15 years
 Yielding total luminosity O(20,000) fb-1
over ~25 years of operation

26. 340 128 Institutes 21 Countries FCC Week 2015 STATISTICS Registrants
FCC kickoff & FCC week 2015 – both had about 340 participants

27. a few highlights from the FCC week
US congressman Bill Foster: “don’t be shy to stand up for the unique nature of your field and don’t be afraid of big numbers!”
special session devoted to US (LARP, SRF, high field magnets, particle physics strategy)
industrial exhibition and “industry fast-track” session focused on Nb3Sn and HTS conductor development
James Siegrist (DOE) pointed way for aligning the US high-field R&D effort with FCC goals; implementation plan to be composed in near future
first US demonstrator magnet could be ready in 2016
Lenoid Rivkin was confirmed as FCC collaboration board chair until the end of 2018

28. Outlook till end 2015 freeze baselines, parameters and concepts
colliders, injectors and infrastructures
series of (mini-)reviews in June and September/October:
- geology, FCC-ee optics, FCC-hh injection energy
put Nb3Sn/16 T magnet program on solid feet
alignment with US DOE high-field magnet program
define and launch selected technology R&D programmes
e.g. cryo-beam vacuum system for FCC-hh
reinforce physics and detector simulations
pursue MDI ( e.g. FCC-ee SR effects) and experiment studies
further enlarge global FCC collaboration
