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 R&D 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 R&D. 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 R&D 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 R&D that will take place in the Integrating Activity and of other R&D 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

Proposed Second Level Work Breakdown Structure for the NA

WP1 Management & coordination

WP2 Getting the 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 - Choices of the facility(es) and proposal

A more detailed breakdown is in preparation

!!!!!!


Four years of BENE in a nutshell

• 2004 BENE established on the EU scene

• MMW workshop May 2004: the MMW frontier Villars SPSC meeting Sep 04, where

we cashed

renewed attention to a Eu ν program (R&D)

emergence of a ν “construction window” !!!!!!!!!!! Betabeam DS approved !• 2005 BENE consolidated on the EU & international scene

– NNN05 in April and NuFact05 in June physics case further established in the two workshops

R&D advancing :HARP+MUSCAT data out, MERIT+MICE approved,

making the ν case in the strategic discussion ahead

• 2006 BENE proved a driving force of the International Scoping Study with US+Japan+India and more published a comprehensive Midterm Scientific Report CERN Yellow 2006-005 22 May 2006

scored in July a “formal” CERN Council recognition of its physics case, its R&D recommendations started an intense period of preparation of FP7 proposals

• 2007 BENE Design Study Euro-ν approved in August in a natural international context the International Design Stud(ies) Neutrino Factory IDS CERN Mar 07, next Jan 08
