CLIC near CERN Tunnel implementations (laser straight) Central MDI & Interaction Region
Physics at LC from 250 GeV to 3000 GeV • Physics case for the Linear Collider: • Higgs physics (SM and non-SM) • Top • SUSY • Higgs strong interactions • New Z’ sector • Contact interactions • Extra dimensions • …. AOP (any other physics) … • Specific challenges for CLIC studies: • Need to address Higgs-studies, including gains for measurements at higher energies • Reach for various “new physics” (list above) options; comparative studies with HiLumi LHCand proton-proton at higher energies (FCC).

Construction Phase Stage 1 construction of CLIC, in parallel with detector construction. Preparation for implementation of further stages. 2013-18Development Phase Develop a Project Plan for a staged implementation in agreement with LHC findings; further technical developments with industry, performance studies for accelerator parts and systems, as well as for detectors. 4-5 year Preparation Phase Finalise implementation parameters, Drive Beam Facility and other system verifications, site authorisation and preparation for industrial procurement. Prepare detailed Technical Proposals for the detector-systems. Critical issues for next phase: Design and Implementation studies: • CDR status: not optimized except at 3 TeV and not adjusted for Higgs discovery, not optimized cost, first power/energy estimates without time for reductions, limited industrial costing, very limited reliability studies X-band developments: • CDR status: Single elements demonstrated – limited by test-capacity System-tests: • CDR status: CTF3 results initial phase (as of early 2012), ATF and FACET very little, no convincing strategy for further system verification, programmes for use of Xbandtechology for other applications in its infancy • CDR status concerning drive-beam FE: Nothing done beyond CTF3 Technology developments: • CDR status: alignment/stability partly covered, BBA assumed, wakefieldmon.perf. assumed, no complete module Commissioning Becoming ready for data-taking as the LHC programmereaches completion. 2018-19 Decisions On the basis of LHC dataand Project Plans (for CLIC and other potential projects), take decisions about next project(s) at the Energy Frontier. 2024-25 Construction StartReady for full construction and main tunnel excavation.
