Status Report from BENEV. Palladino, CARESG, College de France, Sep 5 2005

• 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 data out, MERIT+MICE approved, ISS launched) full recognition of BENE at CERN as the ν center of initiative

the ν voice in the strategic discussion ahead

CARE-Report-04-034-BENE.docCARE-Report-05-021-BENE.doc


proud to have gotten this far

Matching our two crucial 2005 milestones • Physics case developped as far as possible today

in the most international context possiblebecoming a polished BENE Interim report

• Design Study road traced by ISS

in spite of outstanding difficulties small size of our community & its core of active people

cern contribution being resurrected only now (slowly)

division that makes at times consensus unnecessarily difficult

NB legitimate different scientific interests do exist

BENE+EURISOL



positive signals , after meager years of LHC crisis

1) EU approval (HIPPI and BENE)

Main conclusion

MMW and ’sback on the EU map, maybe

2) attention of CERN & National Agencies …. more vigourous R&D soon maybe

can CERN envisage a high intensity (M-MW) frontier

besides its high energy (M-TeV) frontier ? undisputed mandate


Second conclusion

A rich program appears possible around a SPL (Superconductive Proton Linac)

but it may with other proton drivers too, like a RCS, most likely (Rapid Cycling Synchrotron)

two options

1) high energy ……. NuFact (& Superbeam)

2) low energy …….. Betabeam (& Superbeam)


Third conclusion …. a question

LHC (& upgrade) will be the first priority

Next HE project .. CLIC

Will there be a window for a MMW investment?



Two main physics strategies

use of the high neutrino rate (>1020/year) and energy (10-50 GeV) of Neutrino Factory + LMD detector of large but not huge mass (50-100 Kt), necessarily magnetic (a dense magnetized Iron detector, or, possibly, Li-Argon), a few 1000 Km away.

use of the lower neutrino rate (1018-19/year) and energy (sub-GeV) of Betabeam + Megaton low density detector of very large mass (0.5-1 Mt) and volume (0.5-1 Mm3) non magnetic (a Water Cerenkov detector, or possibly, again Li-Argon), a few 100 Km away.

Superbeam (high power conventional beams)

is less performing, per se

but does have technical synergy with the NuFact largely coincides with the front end of a Factory

solving the technical challenges of a several MegaWatt proton driver and target & collection system, on the way to build a factory, yields a superbeam facility essentially for free (not its detector, however!)

and does have scientific synergy with the Betabeam can use the same detector combination has some truely unique features: 1) oscillation signal is νe→νμ in the first, νμ→νe. in the second, one calibrates the signal (and background) of the other !

2) T-reversal and CPT asymmetries can be measured likely to be integrated in both strategies

ν


Esample of comparison of physics reach: CP violating phase

Figure 7 : 99%CL sensitivity of the beta-beam, of the SPL-SuperBeam, and of their combination, see text. Dotted line is the combined Superbeam+beta-beam sensitivity computed for sign(m2)=-1. Sensitivities are compared with a 50 GeV Neutrino Factory producing 21020 decays/straight section/year, and two 40 kton detectors at 3000 and 7000 km

Comparable merits : NuFact somewhat better and more versatile for ν oscillations Megaton offers sinergy with N decay and more

NB conclusions highly preliminary based on still not well agreed yardsticks must now be re-scrutinized much more in depth (ISS)

!!!


Betabeam + Megaton NuFact + LMD

are complementary !!!!!!!!!!! each has merits unaccesible to the other (matter effects, CP, T , CPT violation, p decay, astroph. & cosmology .. )

by means of truely international collaboration we could and should aim at having both facilities

A general remark

and

we must push both very actively catch opportunities wherever they emerge

seriously aim at building one in Europe in the “construction window”

!!


Further caveat

Intermediate solutions also emerging !

Higher energy and higher rate betabeams heading to detectors at intermediate distances

thou technically more difficult ( beta acceleration in new higher energy SPS or LHC !) do deserve very careful attention

A joint venture, jointly set up by the coordinators of the US Neutrino Factory Collaboration the Japanese NuFact-J Work Group

the Eu BENE Network and the host (RAL) UKNF Collaboration

to lay the foundation of a full blown International Design Study

that must advance to same level of progress as Betabeams

Physics

compare performance of various options on equal footing of parameters and conventionsand agreed standards of resolutions, simulation etc.

identify tools needed to do so (e.g. Globes upgraded?)

propose « best values » of baselines, beam energies etc..

Accelerator: -- proton driver (energy, time structure and consequences)-- target and capture (chose target and capture system) -- phase rotation and cooling -- acceleration and storage

evaluate economic interplays and risksinclude a measure of costing and safety assessment

One crucial task of BENE in the ISS year

assemble a real EDS (Eu DesignStudy) collaboration !!!!! that will sign and provide the manpower & largest part of the funds, matching funds, for a FP7 bid able to have the blessing of ECFA and good odds of approval in Brussels.

find the synthesis of so far not obviously converging interests CERN, INFN, CCLRC, IN2P3, CEA, PPARC, CSIC, Germany?,

Belgium, NIKHEF, everybody

CERN positive attitude towards the ISS and BENE’s initiative willingness to assemble a small ISS task force (R. Garoby) will no doubt greatly help

Coordinator: V. PalladinoDeputy coordinator: E. Gschwendtner

BENE is a Networking Activity (N3) in the framework of CARE

(Coordinated Accelerator R&D in Europe).

Main Objectives

The aim of this Networking Activity is to integrate and coordinate the activities of the accelerator and particle physics communities working together, in a worldwide context, towards achieving superior neutrino beam facilities for Europe. The final objectives are:to establish a road map for upgrade of our present facility and the design and construction of new ones; to assemble a community capable of sustaining the technical realisation and scientific exploitation of these facilities; to establish and propose the necessary R&D efforts to achieve these goals.
