What is KM3NeT ?
Future cubic-kilometre scale neutrino telescope in the Mediterranean Sea
Exceeds Northern-hemisphere telescopes by factor ~50 in sensitivity
Exceeds IceCube sensitivity by substantial factor
Scientific interest: - Neutrino astronomy (core
energy range: 1 to 100 TeV )
- Dark Matter
- neutrino studies (cross sections, oscillations, …)
- exotics (monopoles, …)

KM3NeT Progress and Status
Technical:
- Design Study 2006-2009 (EU-funded with 9 M€)
- Conceptual Design Report 2008
- Technical Design Report 2009
Political:
- Pilot projects ANTARES and NEMO are CERN RE’s
- High priority on ApPEC/ASPERAand ASTRONET roadmaps
- On ESFRI 2006/08 roadmaps
- Funding commitments(partly conditional to site)

Possible CERN Roles
Recognised experiment (RE)
Structural support with limited resources(reviewing and advisory role)
Structural support with moderate resources(consolidating role in technology and site choices, project organisation etc., member of consortium)
Involvement with significant resources(contribution to preparation and construction,leading member of consortium)
