2. 2 Tunnel implementations (laser straight) Central MDI & Interaction Region CLIC near CERN For CLIC five main priorities have been identified for 2018: A re-baselined staged project implementation, cost and power optimisation – increased industrialisation effort High Gradient structure development and significantly increased test-capacity for RF-structures The systemtest programmes in CTF3, at ATF and in FACET, as well as exploring systemtests in collaborative programmes with light-source laboratories Technical systems developments, related among others to complete modules, alignment/stability, instrumentation and power sources Physics studies related to energy frontier capabilities Schulte (Design), Lebrun (Implementation) Wuensch (Xband) Corsini (Systemtests) Schmickler (Technical Developments)

7. LC organisation 7 Strongly support the Japanese initiative to construct a linear collider as a staged project in Japan Prepare CLIC machine and detectors as an option for a future high-energy linear collider at CERN Further improve collaboration between CLIC and ILC machine experts Move towards a “more normal” structure of collaboration in the detector community to prepare for the construction of two high- performance detectors

9. Main activities and goals for 2018 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 Baseline design and staging strategy Solid cost basis and more optimized power/energy (aim for 20% energy reduction) Proof of industry basis for key components/units, in particular those specific for CLIC Comprehensive reliability/robustness/uptime analysis Pursue increased use of X-band for other machines/applications 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 Baseline design and staging strategy Solid cost basis and more optimized power/energy (aim for 20% energy reduction) Proof of industry basis for key components/units, in particular those specific for CLIC Comprehensive reliability/robustness/uptime analysis Pursue increased use of X-band for other machines/applications System-tests: CDR status: CTF3 results initial phase (as of early 2012), ATF and FACET very little, no convincing strategy for further system verification Complete system-tests foreseen for next phase, and comprehensive documentation of the results at CERN (CTF3) and elsewhere Strategy for further system verification before construction (XFEL, connected to light-sources, further drive-beam verifications) or as part of initial machine strategy.
