EUROnu Introduction and Objectives • Neutrino oscillations: much interest since 1 st paper in 1998 - extension required to SM - possible explanation of matter-antimatter asymm. - contribution to dark matter - may bring explanation of hierarchy problem - etc • Many projects World-wide to make new measurements • Much theoretical interest • In Europe: CNGS T 2 K Double Chooz etc • Despite these, full picture looks to require new facilities conventional Super-Beams Neutrino Factory Beta Beam EUROnu Review: 14 th April 2011
EUROnu Introduction and Objectives • Much interest in Europe in these facilities • Possible to host both accelerators and detectors: Accelerators: CERN & RAL Detectors: many places – see LAGUNA DS! • Prior to EUROnu: work undertaken largely independently • EUROnu created to: - bring together groups working on facilities - undertake crucial R&D on accelerators - compare performance, “cost”, safety and risk in same framework - report results to CERN Council + elsewhere • Aim is that all of EUROnu (+ others) continue to next step EUROnu Review: 14 th April 2011

WP 2: Super-Beam • Conventional Super-Beam: - similar to existing beams - but higher beam power and bigger detectors • Particular focus in EUROnu: CERN to Frejus EUROnu Review: 14 th April 2011
WP 2: Super-Beam Coordination: CEA & CNRS STFC & CUT CNRS CEA EUROnu Review: 14 th April 2011

WP 3: Neutrino Factory Coordination: Imperial Work being done in close collaboration with International Design Study for a Neutrino Factory STFC Warwick STFC, CERN, Imperial, UOXF. DL, Warwick STFC, Imperial EUROnu Review: 14 th April 2011
WP 4: Beta Beam • Studied in EURISOL FP 6 DS • Looked at 6 He and 18 Ne – but couldn’t make enough Ne • EUROnu: 8 Li and 8 B; increase 18 Ne production • Plus bunching, capture, acceleration and decay ring EUROnu Review: 14 th April 2011
WP 4: Beta Beam Coordination: CERN INFN, UCL CNRS EUROnu Review: 14 th April 2011 CEA, CERN

WP 5: Detectors • Near detectors: - measure flux and beam composition - measure cross-sections - measure charm background do physics EUROnu Review: 14 th April 2011 - Glasgow, Uni. Sofia
WP 6: Physics Reach • Brings together information from other work packages • Treats it independently and consistently Coordination: CSIC • Physics performance • Optimisation CSIC, UDUR, INFN, MPG • Systematic uncertainties CSIC, UDUR, INFN, MPG • Physics comparison CSIC, CERN, UDUR, INFN CSIC, INFN, MPG EUROnu Review: 14 th April 2011

Costing • Requirement is to do relative cost estimate of facilities • Best accuracy within resources available • Costing panel has been created • Work so far: - existing CERN costing tool being used - use existing costs where possible - common WBS - WBS for WP 2 -5 quite advanced • Workshop in May: - finalise WBS - start entering information in costing tool. • Costing done in common way to improve relative error EUROnu Review: 14 th April 2011
Safety and Risk • Safety assessment: - no point in designing facility if can’t build it! • Main safety issues of facilities identified • Only time to look at large structures, e. g. target stations • Implication of safety on cost and/or performance assessed • Safety panel created - safety workshop in June • Technical risk – will come out of R&D • At the end of EUROnu: - some hardware R&D projects not finished - new hardware R&D identified by DS - some performance unknown • Result to be entered in risk register - implications on cost and/or performance included EUROnu Review: 14 th April 2011
Objectives Objective Delivery date Define facility comparison criteria Undertake interim facility performance for Project Review 18 Produce a reference design of each facility 42 Undertake a physics and cost comparison Write a design report for each facility and publish outcome 46 EUROnu Review: 14 th April 2011 36 48
Criteria • Physics performance – sensitivity to - θ 13 - sign of Δm 223 - δCP - unless θ 13 measured, will be done in ranges of θ 13 • Relative cost • Safety and implications on cost and/or performance • Technical risk and implications on cost and/or performance • In principle, figure-of-merit based on these possible • Unlikely to be helpful! EUROnu Review: 14 th April 2011
Conclusions • EUROnu has brought together EU and world groups working on next generation of neutrino facilities - CERN to Frejus Super-Beam - Neutrino Factory - CERN based Beta Beam • Focus on crucial R&D for each • Aim is to do a comparison • Report results to policy making bodies in Europe and World • Help to determine next steps for neutrino physics • Work is progressing well • All objectives will be met by end of project EUROnu Review: 14 th April 2011
