  1. KM3NeT L. Moscoso DAPNIA/SPP CEA/Saclay - L. Moscoso - KM3NeT

  2. p  qc=43°  m n Detection principle Huge detection volume: km3 Shielded against cosmic rays - L. Moscoso - KM3NeT

  3. Astronomy • Quasars • Gamma-ray bursts • Microquasars • Pulsars • SNR • Cosmology/ particle physics • Dark matter Scientific topics The Mediterranean is well suited to observe the Galactic Centre. Results from H.E.S.S. are encouraging. - L. Moscoso - KM3NeT

  4. Neutrinos from the GC HESS observations - Energy spectrum Aharonian et al.,A&A 425, L13-L17 (2004) dF/dEg = F0 E- with a= 2.2F0 = 1.1×10-4 m-2 s-1 GeV-1 Km3 detector sensitive to a neutrino flux = gamma-ray flux - L. Moscoso - KM3NeT

  5. HESS scan of the Galactic centre - L. Moscoso - KM3NeT

  6. Possible combined observations • Neutrinos from galactic centre detectable in KM3NeT in a few weeks to years (Crocker, Melia, Volkas, Astrophys. J. 622 (2005) L37-40); • Other HESS observations like RX J1713.7-3946 and PSR B1509- 58 in the GC proximity are promising; • Integral and Swift are flying. Swift has reported 42 GRB in 6 months. Hopefully new space detectors in 2010-2020 - L. Moscoso - KM3NeT

  7. Nemo Phase 1 Geoseismic station SN-1 (INGV) Shore station 5 km e.o. cable 21 km e.o. Cable with single steel shield J J BU J 2.5 km e.o. Cable with double steel shield 5 km e.o. cable • 10 optical fibres standard ITU- T G-652 • 6 electrical conductors  4 mm2 - L. Moscoso - KM3NeT

  8. Nestor prototype results Recently published: G. Aggouras et al. Astropart. Phys. 23 (2005) 377 Zenith angle distribution - L. Moscoso - KM3NeT

  9. MILOM Antares: MILOM & Line 0 Line 0 – Cable test Almost a complete line (23 storeys) No electronics Study optical fibre transmission Autonomous recording devices (Tinytags) and measurements from the shore (master electro-optical and interlink cables) No water leaks in electronics containers Successful deployment-recovery-check-deployment-connection-recovery Good and constant conductivity and insulation Optical transmission losses at a number of locations (in the containers) Final versionof the electronics - L. Moscoso - KM3NeT

  10. Antares: The Junction Box JB stable since 30 months. - L. Moscoso - KM3NeT

  11. Antares MILOM: Timing resolution s  0.75ns  for one PMT s 0.75/2 •  0.5ns Will allow a 0.2° pointing resolution - L. Moscoso - KM3NeT

  12. Charge distribution (baseline subtracted) Single photo-electron peak Single pe signal wave-form 640MHz sampling Antares-MILOM: ARS responses Main clock - L. Moscoso - KM3NeT

Sheffield Particle/Astroparticle institutes (17) Sea science/technology institutes (7) Coordinator - L. Moscoso - KM3NeT

  14. KM3NeT Design Study: Resources • Suggested overall budget of the Design Study: 24 M€(mainly personnel, but also equipment, consumables, travel etc.). • Amount requested from EU: 10 M€; • Estimated overall labor power: ~3500 FTEMs(FTEM = full-time equivalent person month)→ 100 persons working full-time over 3 years! Substantial resources (labor power) additional to those available in the current pilot projects will be required ! - L. Moscoso - KM3NeT

  15. The KM3NeT Design Study: Milestones • Proposal submission 04.03.2004. • Evaluation report received June 2004 (overall mark: 88%). • Unofficial but reliable message (Sept. 2004):The KM3NeT Design Study will be funded ! • Currently waiting for EU call to negotiation. Negotiations expected between summer and end 2005 • KM3NeT in the ESFRI “List of opportunities” • Strong support is asked to the funding agencies - L. Moscoso - KM3NeT

  16. KM3NeT Consortium • Organizational structure (phase 1): • Negotiation Preparation Group (NPG).Task: preparation of the consortium agreement • Major legislative body: General Assembly;One representative per institute;Simple set of rules for phase 1 worked out by NPG.Task: Approval of all documents, commitments, ... • Coordinator: U. Katz confirmed. In permanent contact with Brussels. • WP responsibles: named by “Leading Institutes”Task: establish communication between WP partners,collect info., contact persons for NPG, WP summaries - L. Moscoso - KM3NeT

  17. Working packages - L. Moscoso - KM3NeT

  18. Time line • 24/25 Feb. 2005: First meeting of NPG; • 1 March 2005: Nomination of all WP coordinators approval by GA; • 14-15 June 2005:Second meeting of NPG; • End June 2005: Guideline for WP coordinators; • 5 Sept. 2005: First common meeting of NPG and WP coordinators; (few pages, detailing plans, resources, ...); • 8-11 Nov. 2005: Second VLVnT workshop, Catania. - L. Moscoso - KM3NeT

  19. Conclusions (1) • HE neutrino observation is essential to achieve multi- messenger and multi-wavelength astronomy; • An equipped volume of at least one km3 is necessary; • The Mediterranean Sea allows us to observe the Galactic Centre; • FP6 Design Study will combine the efforts of the three pilot projects Antares, Nemo, Nestor; - L. Moscoso - KM3NeT

  20. Conclusions (2) The balance of these last few months is very positive: • Scientific point of view • The recent HESS observations in the TeV range are very encouraging; • Political point of view • ESFRI adds KM3NeT to “List of opportunities”; • The funding agencies show their intention to reinforce their support to the pilot projects; • New institutes (not present in the 3 pilot projects) have joined KM3NeT; • Technical point of view • The recent results with the new Antares prototypes are an important progress. - L. Moscoso - KM3NeT
