Phase 1 History Foreseen Realized so far 24 ARCA DUs 6 ORCA DUs

Phase 1 CTF: Cable Termination (Frame) : Secondary Junction boxes : Tower DU : String DU PPM-DU EMSO node

Phase 1 (the bad) Main failures occurred in the last year ARCA DU 3 ARCA Junction Box Phase-1 ORCA Cable ARCA system Investigation of failures allowed to find and solve several problems But last failure still without solution (money and vessel unavailability to survey the site and to try to recover bypass the failure and recover the system)

Phase 1 (the goods) ARCA DU3 JB Phase-1 ORCA Cable Modified grounding scheme inside the DOM Improved design of the VEOC (dedicated assembly tools realized by NIKHEF+LNS) JB Phase-1 Needs to be redesigned – contacts with MacArteney ORCA Cable Problem understood – it could represent, necessary to find a definite solution – contacts with Alcatel ORCA DUs are an improved version

Phase 1 (the goods) ORCA-DU1 and ORCA-DU2 ready for deployment (waiting for stable weather conditions)

Phase 1 (the goods) ARCA-DU1 and ARCA-DU2 deployed December 2015 and May 2016 at Capo Passero, Sicily worked till April 2017 plenty of statistics Data analysis of atmospheric muons shows excellent agreeement between data and MonteCarlo

Phase 1 (the goods)

Phase 1 Summary Early «infant mortality» intrinsic of any starting project (obviously we cannot exaggerate!) Several lessons learned Quality of DUs highly improved Quality Assurance generally improved The detectors performances are well under control

Phase 2 Budget France: 8 M€ secured, new request for 20 M€ ongoing Italy: POR Sicilia 34.5M€ secured (50% INFN co-funded) The Netherlands: new request for 12.7 M€. Decision in 2018 Italy: PON IR 16 M€

Phase 2 ARCA: Astronomy Research with Cosmics in the Abyss To be installed in the Italian site of the KM3NeT infrastructure 115 detection units per building block 18 DOM per DU Vertical DOM spacing 36 m Inter-DU spacing 90 m 2 building blocks Total volume ≈1 km3

Phase 2 The production and integration rates have been defined to complete the construction in 2022

Phase 2 PMTs The specifications for the PMT tender have been defined The tender is expected to start shortly ARCA cable The definition of the specifications of the Phase 2 - ARCA cable is in progress Review Committee (F. Ameli, M.Circella, R. Cocimano, A. D'Amico, P. Lamare, K. Leismuller, M. Sedita, M.T.) The tender is expected to start this year

Phase 2 Set-up of integration facilities on-going DOM integration sites Catania, Naples, NIKHEF OK Athens, Erlangen, Rabat, Strasbourg in progress DU integration sites LNS, NIKHEF OK Genova in progress Full description in next slide

Report to the President of the INFN Il Comitato di Valutazione Internazionale (CVI) N. Amodio, Confindustria, It; P. BinŽtruy, APC Laboratory, Fr; M. Bosman, IFAE, Barcelona, Es; M.N. Harakeh, KVI-CART, Groningen, ; A. J. S. Smith, Princeton University, USA (chair); C. Spiering, DESY, D; and E. Zaninotto, Università di Trento, I December, 2016 CSN2 KM3NeT: The failure of the 3rd string is a reason of concern (although the string was recovered and the problems identified). However, its strategic importance is very high so INFN should continue to support it, and consider postponing the tower deployment for the moment to continue with strings first. In this way the decisione on best use of the towers (e.g. for a dense core) can be made without time pressure

In Sicilia operano i principali EPR Nazionali In Sicilia operano i principali EPR Nazionali. Nel dicembre 2014 call per «INVITO A PRESENTARE MANIFESTAZIONI DI INTERESSE PER L’INSERIMENTO NELLA RETE DELLE INFRASTRUTTURE DI RICERCA DEL PIANO NAZIONALE DELLE INFRASTRUTTURE DI RICERCA- PNIR» Il Contesto Le prime 3 I.R. della graduatoria sono state inserite nel PNIR. Nel PNIR sono state, inoltre, individuate le I.R. ritenute strategiche per il paese (17) tra cui i LNS (Laboratori Nazionali del Sud) e KM3NeT. KM3NeT è l’unica infrastruttura con sede in Sicilia ad essere inserita nella nuova road map ESFRI (2016-2020)

Il Laboratorio Multidisciplinare Distribuito sul Mare Messina Roosevelt Catania Capo Granitola Portopalo

Il Laboratorio Multidisciplinare Distribuito sul Mare Il Laboratorio è stato indicato dalla Regione Siciliana come l’I.R. a più alta priorità strategica da inserire internamente al PNIR (Piano Nazionale delle Infrastrutture di Ricerca). KM3NeT è una parte fondamentale di questo Laboratorio che coinvolge i principali EPR Italiani.

Finanziamento POR Regione Siciliana (scadenza 31/12/2019) Progetto INFN-INGV-CNR: 40 M€ cofinanziato al 50% dalla Regione INFN 34.5 M€, INGV 5 M€, CNR 0.5 M€. Per INFN 2.15 M€ da Premiale Labmed, 14 M€ da Foe Esfri Km3NeT (2016-2019), Personale 0.6 M€,Budget LNS 0.5 M€. Il programma di attività è stato definito assieme al management di Km3NeT.
