Proposal of an FP7 accelerator neutrino
Networking Activity The European Strategy for
Particle Physics emphasizes the importance of
accelerator-based neutrino experiments, and sets
the milestone for the next major undertaking in
this field in 2012 Studies of the scientific
case for future neutrino facilities and the RD
into associated technologies are required to be
in a position to define the optimal neutrino
program based on the information available in
around 2012. A vigorous networking activity is
necessary to ensure that the technical
information on accelerator technologies and the
scientific arguments are gathered, developed, and
discussed within and outside the neutrino
community. The NA intends to deliver at the
end of 2012 an agreed programme of neutrino
experiments, based on upgrades of existing
infrastructures and/or on the proposal of a new
one. Among the possibilities the following will
be considered and evaluated. -Upgrade of the
existing Cern to Gran Sasso facility
understanding of the ultimate upgrade potential,
by combination of improved neutrino flux,
neutrino spectra, flux monitoring abilities and
far detector design and location. -A new
neutrino facility, such as a beta-beam or a
neutrino factory complex, offering much higher
rate and purer flavour content, allowing a more
ambitious programme of complete determination of
the physical quantities governing neutrino
oscillations mass splits, flavour mixings and
charge-parity violating phase. The NA will be
rooted in the FP6 BENE NA, active since 2004,
itself born from the ECFA Study Groups active
since 1998. The existence of an organized open
discussion and dissemination forum joining the EU
accelerator particle physicists active or being
attracted in the sector has proven decisive over
almost a decade. The European activity is
embedded in an international effort most
remarkable are the yearly NuFact International
Workshops on Neutrino Factory, Superbeam and
BetaBeam. Started in 1999 in Europe and
returning every three years, it is an extremely
fruitful example of collaboration of accelerator
and particle physics from Europe, America and
Asia.. Strengthened by FP6 support, BENE
achieved the recognition in the Strategy Document
of its physics case and of its plea for timely
RD. Its 3 main goals are also being delivered
as promised -first progress in community
building and harmonization of national projects
and interests. - preliminary road map towards
the scientific technical choice of the new
facility -precious collaborative studies and
RD projects now under way, soon including the
FP7 EuroNu DS and the International Design Study
effort. The objective of this NA represents the
natural completion of this process. The NA will
be able to integrate in its proposal the results
of a CNGS upgrade study, of the EuroNu design
study of the Neutrino Factory, Superbeam and
BetaBeam options, of the state of the art,
coordinated RD that will take place in the
Integrating Activity and of other RD projects in
progress. Its final proposal should be backed by
the widest possible majority of the EU community
active in on neutrino accelerator infrastructures
worldwide, at the CNGS, at the US (NuMI) and at
the upcoming Japanese (T2K) facilities. The NA
funds will support participation of this
community to -the IA meetings and the NA own
plenary meetings and parallel workshops -the open
meetings of the EuroNu DS -the yearly
international NuFact Workshop

most of existing neutrino facilities - CNGS
intensity limits - possibility of adaptation
of the CNGS neutrino spectrum and of flux
monitoring to physics needs
(link to JRAs in FP7-IA) - Evaluation of the
physics potential of upgrades WP3 Road map
to the future - evaluation of the
compatibility of future neutrino facilities to
the accelerator upgrades in the
interested European laboratories -
evaluation of technological risks of the proposed
options - evaluation of the
synergies with other physics programs
- upgrade path and flexibility -
