EUROEUROA High Intensity Neutrino Oscillation Facility in
Europe
• Introduction
• What EUROnu is doing
• Next step
• Input to the Strategy Review
• Future of EUROnu
• Conclusions
On behalf of the EUROnu Consortium
EUROnuEUROnu
• FP7 Design Study
• Due to limited funds: focus on possible “next” generationneutrino oscillation facilities in Europe
• Do:
Conceptual designs of accelerators
Performance of baseline detectors
Physics performance
Approximate costs
• Project started: 1st September 2008
• Duration: 4 years – completion in August 2012

EUROnu WorkEUROnu Work
• Three facilities
• CERN to Frejus Superbeam:
Based on 4 MW SPL
Targets, horns, integration and target station
Beam preparation for targets

MEMPHYS detector at Frejus
• Much of the work is generic Marcos Dracos, Marco Zito, et al

Neutrino FactoryNeutrino Factory
• Close collaboration with IDS-NF
• EUROnu: target to muon acceleration
• Aim: Reference Design Report
• Detectors: MIND + near detector(s)
• Baseline redefined following θ13: 10 GeV instead of 25 GeV
cheaper
easier to build

Beta-BeamBeta-Beam
• Main issue in EUROnu: maximise ion flux in SR
• Studied:
new ion species
alternative production methods
collective effects
collection
bunching
acceleration
storage
• 2 ion options considered: - 6He & 18Ne → from EURISOL - 8Li & 8B
→ from C. Rubbia et al

DetectorsDetectors
• Limited funding: only performance and cost
• Concentrate on baseline detectors
Magnetised Iron Neutrino Detector - NF
Large water cherenkov – SB and BB
Near detectors
• Extrapolations from existing technology, not new
Paul Soler, Anselmo Cervera,
et al
PhysicsPhysics
• Physics performance determination
• Done independently of facilities, as it should be
• As far as possible
everything done in a consistent manner
including systematics
migration matrices
• First comparison from Enrique Fernandez-Martinez & Pilar Coloma
Pilar Hernandez, Andrea Donini, et
al

CostingCosting
• Doing the best we can with limited resources
• Using CERN costing tool – developed for CLIC
• Using as much existing knowledge as possible
• Being done in a consistent manner: - Same assumptions - Same costs, where possible
• Using CERN as the location
• Civil engineering is a significant component
• All facilities have been laid out at CERN

Next StepsNext Steps
• EUROnu finishes in 3.5 months
• FP7 final reports are limited
• Special EUROnu edition of:Physical Review Special Topics: Accelerators & Beams
• Papers:- Introduction- Overview of each facility & detectors -
Special papers on specific work
• Introduction – EUROnu summary for Strategy Review?
• Deadline for Overview papers: 31st July!
Input to Strategy ReviewInput to Strategy Review
• Date of EUROnu annual meeting: 12th-15th June
• Fixed and announced about a year ago
• First and only opportunity for EUROnu to discuss SR
• Fortunately: 6 weeks to submission deadline
• EUROnu future:
Aim: proponents of future facilities working together
Has worked well
Would like to continue
Depends to some extent on new CERN Strategy
Appropriate programme in Horizon 2020 (~FP8)
ConclusionsConclusions
• EUROnu has been running for almost 4 years
• Much detailed work done
• Physics parameters much more reliable and defendable now
• What needs to be done after EUROnu is known
• Work coming to an end
• Main things still to be done:
Complete modifications for large θ13
Complete costing
Write everything up
Decide on future
• It has been a pleasure to coordinate the project!
