The International Scoping Study
a step on the way!

• One-year study NuFact05 NuFact06
• Built on previous work
• Super beam
• CERN MW w/s, studies in US and Japan
• Beta beam
• EU Study supported by EU under FP6
• Neutrino Factory
• US Studies I, II, IIa
• ECFA/CERN Study
• NuFact-J Study
• Emphasis
• Incorporate progress made since previous studies
• e.g. MERIT, MICE, MuCOOL, NSFFAG,
• Recognition of importance of holistic
  consideration of source and detector
• Recognition of importance of an international
  approach

ISS organisation

• Parallel study of
• Physics performance
• Accelerator facility
• Neutrino Detectors

• International participation
• Programme committee and working groups

4
ISS outcomes

• Principal outcomes
• Defined baselines for Neutrino Factory
  accelerator and detector systems
• Established importance of
• Low muon-detection threshold for ?e ? ??
  (golden) channel
• New analysis of magnetised-iron calorimeter gives
  good performance
• ?e ? ?? (silver) and ?? ? ?e (platinum)
  channels essential to search for non-S?M
  processes
• e.g. non-unitarity of MNS matrix
• Comparison of sensitivity of various options
• Report in preparation

The ISS baseline

• 100 (50) kT magnetised iron detector
• Two baselines
• 3000 5000 km
• 7000 8000 km

• Store µ µ- simultaneously
• 1021 muon decays/yr
• Eµ 25 GeV

The International Design Study
initiative

• NuFact06
• Made the case for high-sensitivity
  neutrino-oscillation programme for second half of
  next decade and concluded

10
NuFact06 recommendation

• Neutrino Factory IDS
• Continue holistic approach of ISS
• Goal deliver Neutrino Factory CDR by 2012

11
Strategic review conclusions

• Reviews of particle-physics strategy in Europe
  and the US concluded that
• Future neutrino programme be developed as an
  internationally coordinated programme
• Goal to define the optimal programme around
  2012
• NuFact community aspiration matches this

ISS/IDS transition as seen at NuFact06

• Progress since NuFact06
• IDS initiative (transition phase) established
• EU FP7 DS (Euro?) submitted
• Ranked 1, now negotiating contract
• See M.Lindroos, WG3, Tuesday, 1500
• IDS initiative now drawing to an end
• Goal to launch IDS at this meeting NuFact07

IDS goals

• Goal of NF IDS
• Neutrino Factory RDR (2012)
• Engineering designs for most components
• Neutrino Factory IDR (2010)
• Marks transition from
• Concept development/RD with engineering support
  to
• Significant engineering effort with
  concept-development/RD programmes to mitigate
  risks

IDS-NF steering group activities

• Second IDS-NF plenary meeting
• 1617 January 2008, RAL
• Aims
• Establish the IDS-NF programme and set the goals
  for the study over the period January 2008 to
  NuFact08
• At NuFact08 need to be ready with a longer term
  plan
