• Branching point for continuation Recommendations of the European Strategy Group at end 2012/beginning 2013 Updated Scientific Strategy of CERN by new DG: 2014?

Key ingredients for continuation:- Physics! Based on the results of LHC and of the on-going experiments.- Strength / weaknesses of competing options (Linear collider …)- Strength / weaknesses of the SPL-related applications (Proton drivers for facilities, Injectors for LHC-

related future beyond HL-LHC, LHeC …)- CERN strategy for sc RF technology- Politics and collaborations…

MotivationMotivationTo better match the needs of the medium term goal of the HP-SPL R&D:

Building and testing a prototype cryomodule with 4 cavities

Main principlesMain principles-«Project-like» structure emphasizing relations between contributions (integrated planning)-Main objectives:

- Design, construction and test of the prototype cryomodule- Components: Cryomodule, Cavities, RF items (Couplers, tuners, …), cryogenics equipment…- Assembly (with adequate tools): cavities string in clean room, inclusion in cryomodule- Tests: cavities in vertical cryostat, assembled cryomodule in bunker.

- Experience in SC RF cavities technology- Fabrication and processing- Test, diagnostics and analysis- Upgrade of the SM18 infrastructure- Cryogenics for efficient operation at 2K- High power RF at 704 MHz (klystron, modulator, high power distribution)- Low Level RF and controls
