• 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

Performance

MEMPHYS detector at Frejus

• Much of the work is generic Marcos Dracos, Marco Zito, et al

Super-BeamSuper-Beam


To minimise extrapolation from working facilities:

4 targets and horns



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

Neutrino FactoryLENF



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!
