EW Baryogenesis (from CKM CP violation) has hit
difficulties when Higgs limit exceeded 40 GeV
(1993) the favorite theory is now
Leptogenesis.

TARGET DATE 2010
2010 will be a time of major decisions in
particle physics LHC will be completed first
results will appear ILC ? first results
from MINOS, OPERA double-CHOOZ might be
available. T2K will be starting and very
rapidly dominating! It will be time for the
next step in neutrino physics!

observation and study of CP violation requires
-- all accelerator neutrinos -- high precision
in neutrino vs antineutrino normalization --
redundancy. probably out of reach of these
experiments ? need to go further

4MW, 1 Mton upgrade of T2K
By 2010 we must know how much these facilities
cost and how long they would take to build.

• An ambitious neutrino programme is a distinct
  possibility,
• but it must be well prepared to have a good
  proposal in time for the big decision period in
  2010 (Funding window 2011-2020)
• 2. Two avenues have been identified as promising
• a) SuperBeam Beta-Beam Megaton detector
  (SBBBMD)
• b) Neutrino Factory (NuFact) magnetic detector
  (40kton)
• The physics abilities of the neutrino factory are
  (much) superior
• in particular for flux normalisation
• but..  what is the realistic time scale? 
• 3. (Hardware) cost estimate of a neutrino factory
  1B detectors.
• This needs to be verifed and ascertained on a
  localized scenario (CERN, RAL) and accounting.
• The cost of a (BBSBMD) is not very different,
  though perhaps lower
• Cost/physics performance/feasibility comparison
  needed

The Beta-beam accelerator study is funded within
EURISOL DESIGN STUDY and this is making
impressive progress. (it is still a very new
concept however)
The Neutrino Factory and Superbeam design study
(with RAL as home institute) was prepared for a
EU DS call in 2004 (sub march 2005) which never
took place. It turned out to be too far-fetched
to substitute an I3 proposal to this. In the
process the need to include detector RD was
identified.
Meanwhile
Optimization of the neutrino factory in the US
has led to cost reduction by 40 1B
The target experiment nTOF11 is now approved at
CERN, scheduled to run in 2007
The MICE experiment is now approved at RAL
(recognized as CERN RE11) and scheduled to run
in 2007
There is a proposal for an electron-model FFAG
experiment

Design study

• Design study will take place in two phases
• Scoping study understand what are the most
  important parameters
• of the facility to be studied, what are the
  critical tests to be performed,
• and how to organize it. Assemble the team.
• 2. Design study proceed to the design study and
  associated RD experiments,
• with the aim to deliver a CDR that a laboratory
  can chose as its next project.
• For design study we intend to request EU funding
  probable date spring 2007

It will be WORLD WIDE 1. It is likely that
there will be no more than one Megaton detector
and/or one Neutrino Factory in the world so we
better agree on what we want. 2. Expertise on
Neutrino Factory is limited world-wide (mostly in
US) 3. Resources e.g. at CERN are also very
limited 4. International community meets
regularly at NUFACT meetings and is engaged in
common projects (RD experiments) Muon cooling
exp. MICE at RAL, Target Experiment nTOF11 at CERN

Collaborators of the scoping study --
ECFA/BENE working groups (incl. CERN) (funded by
CARE) -- Japanese Neutrino Factory
Collaboration -- US Neutrino Factory and Muon
collider Collaboration -- UK Neutrino Factory
Collaboration (also part of BENE) -- others (e.g.
India INO collaboration, Canada, China, Corea
...)
objectives Evaluate the physics case for a
second-generation super-beam, a beta-beam
facility and the Neutrino Factory and to present
a critical comparison of their performance
Evaluate the various options for the accelerator
complex with a view to defining a baseline set of
parameters for the sub-systems that can be taken
forward in a subsequent conceptual-design
phase Evaluate the options for the neutrino
detection systems with a view to defining a
baseline set of detection systems to be taken
forward in a subsequent conceptual-design phase.
12
Physics compare performance of various options
on equal footing of parameters and
conventions and agreed standards of resolutions,
simulation etc. identify tools needed to do so
(e.g. Globes upgraded) propose  best values 
of baselines, beam energies etc..
Detectors (NEW!) 1. Water Cherenkov

NB This matches well the time scales set up at
CERN participation of CERN is highly desirable
to ensure that the choices remain
CERN-compatible. This effort is similar to and
synergetic with the PAF and POFPA working groups
at CERN.

Conclusions
I strongly believe that the swiss physics
community should be strongly involved and not
only the 3 mousquetaires (Bern, Geneva,
Neuchatel, Zurich) ? accelerator ..
physics/phenomenology .. detector RD
