Concluding Discussion ISS RAL Meeting Apr 2006

• ISS a one year Study – commenced NuFact05– Ends NuFact06

• To Discuss Now– Focus efforts For the Final Report &

Presentation at NuFact06

– Plan the Next Step after ISS

27 Apr 2006P J Dornan - ISS3 - RAL

The ISS End Game

• Presentation– At NuFact06

• And then it is important that the results are widely distributed

• Report– Before the end of 2006– Based on the 3 Working Groups– What should this include?

27 Apr 2006P J Dornan - ISS3 - RAL

Physics

– The importance of physics– Justification for precision determination of

the oscillation parameters• to the level of the CKM parameters?

– Comparisons of Performance• Superbeam, -Beam, Factory• With various scenarios with appropriate detectors

at suitable baselines

27 Apr 2006P J Dornan - ISS3 - RAL

Physics Report

How important – gold, silver, platinum?

In the ideal scenario should we measure

e→e

→e

Specifically - how important are the tau channels?

27 Apr 2006P J Dornan - ISS3 - RAL

Muon Physics & the Factory

Intense muon beams are needed for muon physics

Could be the place for the next major advance

But - is a Factory suitable for muon experiments?

27 Apr 2006P J Dornan - ISS3 - RAL

Detectors

Which can effectively be magnetised?

Iron calorimeter, Emulsion

Liquid Argon??

How low can one reduce the threshold?

Which can identify taus?This must tie in with the relevance of gold, silver platinum

Cost?

Define the necessary R&D Programme

27 Apr 2006P J Dornan - ISS3 - RAL

Accelerator

This will concentrate on the neutrino factoryA viable baseline design

with realistic parameters and an indication of increase or decrease in performance as one moves from the baseline

Cost & TimescaleCost will not be easy - but even to €0.5BTimescale – Important to show that we could have a precision

neutrino facility by tne end of the next decade

The R&D Programme - MICE, MERIT, + …

27 Apr 2006P J Dornan - ISS3 - RAL

SuperBeams, Synergies

Little discussion on future SuperbeamsIs it assumed problems are understood?

Most synergies centre around the proton driverand it is appreciated that the proton driver used will have more than one application

- but the effort has been to understand the needs of the neutrino factory.

27 Apr 2006P J Dornan - ISS3 - RAL

Incremental Path to a NeutrinoFactory

Era ofsensitivity &

precision

Factory Beam

But Factory and beam can be on same timescale as superbeam upgrades

Path to a NeutrinoFactory or -Beam

27 Apr 2006P J Dornan - ISS3 - RAL

After ISS

• For the precision era– Superbeams, -beams, -Factory will compete for

resources– Could have 0, 1 or 2 Superbeams– plus a-beam or -Factory complex

• Decision Point– 2009-2011– Need a CDR for future neutrino complex by ~2009 -Beam and -Factory– Assume superbeam developments will come from

present proponents

27 Apr 2006P J Dornan - ISS3 - RAL

Neutrino Factory• Following ISS there needs to be a Design

Study for a Neutrino Factory– It will need engineering effort– And therefore resources– Where can these come from?

• Funding Agencies, Labs, EU

– At the BENE/ISS meeting tomorrow planning for a request to the EU FP7 programme will start

• But funding from this source will not come until mid-end 2007– Activity must start before then - it should start

this year• And maintain the momentum of the ISS study

27 Apr 2006P J Dornan - ISS3 - RAL

Organisation of the -Fact Design Study

– Should be decided by NuFact06

• Do we keep a similar structure to the ISS?– Accelerator– Detector– Physics

• How to get organised?

• Can we continue to have it truly international?

27 Apr 2006P J Dornan - ISS3 - RAL

Coherence of the Neutrino Community

• Highly Desirable– Can a -Factory IDS be incorporated with the

broader neutrino community• Superbeams -Beam

-Beam also requires a major R&D effort• Can these both be conducted under the same umbrella

• We have to convince the wider community that the precision age (-Beam or -Factory)

• is feasible and possible by ~2020
