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

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

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
