Conclusion • Well defined CLIC organisation and R&D work program towards feasibility demonstration and CDR edition by end 2010 • Endorsed after detailed scrutiny by Advisory Committee • Under schedule but still lot of work to be done! • Definition of program after 2010 towards TDR by mid 2009: • Requested by Collaboration Institutes • Reflection on work program (task force) • CERN resources planned • CLIC/CTF 3 collaboration very fruitful and expanding • Excellent spirit of competitive collaboration with ILC J.

Strategy for Design & Parameters • Design at 3 Te. V (nominal) and 500 Ge. V (comparison with ILC) • Define range of beam parameters from conservative to nominal at both energies • Conservative beam parameters at 500 Ge. V being demonstrated or addressed somewhere by 2010 • Realistic and optimum 500 Ge. V design • As a fist stage towards nominal energy of 3 Te. V • Optimum parameters and components (Accelerating Structure with reduced accelerating gradient and good efficiency • Larger beam emittances and relaxed tolerances • Realistic scenario of successive upgrades in 4 phases • energy and luminosity • Provide more time for gradual improvement and feasibility demonstration of nominal parameters J.
