  1. TheInternational Design Study for the Neutrino Factory Origins, goals, composition K. Long, 14 August, 2014

  2. History: • Conclusions of the International Scoping Study presented at NuFact06: • Publications: 200 citations to date 62 citations to date 103 citations to date Published, a substantial achievement! • – Physics Report: Rept.Prog.Phys.72:106201,2009. – Accelerator Report: JINST 4:P07001,2009. – Detector Report: JINST 4:T05001,2009

  3. History: towards IDS-NF (and EUROnu): • Initial ‘planning’ discussed at initial meeting at CERN in March 2007: EUROnu submission

  4. EUROnu and the IDS-NF EUROnu BB SB NF • EUROnu is the European contribution to the IDS-NF IDS-NF

  5. IDS-NF mandate from NuFact07:

  6. Progress highlights: accelerator: • Substantial improvements in: • Target, front-end and muon acceleration sub-systems • Other sub-systems have undergone incremental improvement • Indicative of the degree of maturity of the design

  7. Progress highlights: detector: • MIND: • Re-optimised sampling fraction • Cuboid in 1 T dipole field • More realistic field configuration in hand • Detector mass: • Intermediate detector [2500—5000 km]: 100 kT • Far detector [7000—8000 km]: 50 kT • Near detector: • No near detector specified in initial IDS-NF baseline [i.e. ISS Detector W/g report]: • Known to be a shortcoming • IDS-NF near detector concept (baseline 2010/2.0)

  8. IDS-NF baseline 2010-2.0: • Migration matrices (see IDR): • Significant improvement over IDS-NF baseline 2007/1.0

  9. Neutrino Factory performance: • Discovery reach at 3σ extends down to sin22 θ13 ~ 5 x 10-5 • Should θ13 to be shown to be > 0 before start of Neutrino Factory project: • Re-optimisation of baseline: • 10 GeV muon energy serving a single 100 kTon MIND at a baseline of 2000 km gives excellent performance

  11. Conclusions: • The Neutrino Factory: • Best discovery reach • Best precision: • But need to define agreed figure of merit • Best sensitivity to non-standard interactions • The International Design Study for the Neutrino Factory: • Collaboration energetic and ambitious! • IDR 2011; RDR 2012/13 • EUROnu: encompasses and coordinates European contributions • Baseline established and documented in the IDR • Alternatives to baseline retained to mitigate risks • Scientific imperative: • Make the Neutrino Factory an option for the field!
