Geology Studies – Example 93 km

• 90 – 100 km fits geological situation well,better than a smaller ring size

• LHC suitable as potential injector

A key to New Physics

EuroCirCol EU Horizon 2020 Grant

FCC kickoff & FCC week 2015 – both had about 340 participants

• 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

a few highlights from the FCC week

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 collaboration28
