1. KM3NeT-Toulon Infrastructure 22/06/121 NB: focus on latest developments, see February presentation in Catania for details KM3NeT meeting Erlangen, 22-23 June 2012 Claude Vallée for the CPPM group STATUS, PLANS and COSTS of the KM3NeT-Toulon INFRASTRUCTURE

2. KM3NeT-Toulon Infrastructure 22/06/122 Shore station extension designed, submitted to La Seyne city administration. Electrical Power components delivered. Construction/equipment next Autumn Systematic sites characterisation with autonomous lines started in March → site decision early autumn Preferred site Preliminary insight: far site not better than others Preliminary 50cm survey by IFREMER, shows flat and very clean topography.

11. KM3NeT-Toulon Infrastructure 22/06/1211 TOULON SEABED COSTS 700 K€ for installed additional node Significant parts already bought Most of rest based on tenders

12. KM3NeT-Toulon Infrastructure 22/06/1212 Time constraint of the CNRS-EU FEDER funds TOULON SEABED SCHEDULE Deadline for MEOC order: 22 August

13. KM3NeT-Toulon Infrastructure 22/06/1213 SUMMARY and OUTLOOK Design of the Toulon seabed is on schedule and construction+deployment are ready to start. Components and procedures are extrapolated from the experience gained on ANTARES and are well defined. Main open points are finalisation of optical components, adaptation of connectivity to strings and location of AC/DC’s. The seabed is presently financed for max 36 string DUs (1 node). Extension can be made at a moderate cost (700 K€ for 1 additional node → 36 more strings). Critical decision for MEOC order has to be made before 22 August. This necessitates a well defined KM3NeT agreement !
