• 2004 BENE established on the EU scene                    CARE-Report-05-021-BENE.doc



      • 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,

NuFact&Superbeam Design Study
Rob Edgecock(RAL) and Marcos Dracos(IN2P3) have taken the responsibility to start a WG assembling a first skeleton of proposal to be
presented at CARE06 in Frascati (Nov14-17). This was given good priority by ESGARD and is at the moment the most promising immediate
option that we have.

Betabeam Design Study
A DS study is already in progress in the Eurisol framework. Mats Lindroos (CERN) has taken the task to explore within the present DS a first
skeleton of a second phase proposal. At the moment, however, it appears that we will have to delay this to the later FP7 DS call. Mats will
present his present thinking at CARE06

BENE efforts for FP7
Please contact us and join to help
FP7 is finally starting. A first FP7 call, for Design studies, is expected before the end of the year. Proposals will be due in April, a few months later. Approval could bring first funding at the beginnining of
2008 or so.
A second call, for Integrating Activities, is expected Nov 07, with Mar 08 as a deadline, with first funding early 2009. This must contain NAs, TAs, JRAs, see below
Next relevant calls 2009 !!! We should not be stalling for two more years !!
We need the largest possible consensus and coherence. It will clearly not be easy to assemble all the conditions, support from CERN and National agencies and Laboratories, for successful bids.
According to the recent ESGARD/CARE preliminary plan, see http://bene.web.cern.ch/bene/Working-groups_mandate.doc, BENE could file bids for
Two Design Studies (DS): DS’s are studies of feasibility, to be carried out by a European collaboration, funded (presumably for about 1/3?) by EU and working in collaboration with international partners. Recent news
are that the contribution from EC could be larger than originally indicated, as large as 5 M Euros, and R&D work could be included in addition to feasibility studied.
NuFact&Superbeam Design Study
Rob Edgecock(RAL) and Marcos Dracos(IN2P3) have taken the responsibility to start a WG assembling a first skeleton of proposal to be presented at CARE06 in Frascati (Nov14-17). This was given good priority by
ESGARD and is at the moment the most promising immediate option that we have.
Betabeam Design Study
A DS study is already in progress in the Eurisol framework. Mats Lindroos (CERN) has taken the task to explore within the present DS a first skeleton of a second phase proposal. At the moment, however, it appears
that we will have to delay this to the later FP7 DS call. Mats will present his present thinking at CARE06 in Frascati (Nov14-17).
Several Joint Research Activities (JRA), JRA’s are technical R&D projects on realization of key prototypes, demonstrations of performance
and the like, to be carried out by a European collaboration , funded (presumably for about 1/3?) by EU and working in collaboration with
international partners.
Bids for JRA’s should take place within the framework of one of the Integrating Activities that ESGARD intends to promote. Many
LOI’s have been received by ESGARD and more are coming. The task is now the one to select the ones to be actually proposed as JRA’s
within Ia’s. At the moment, three IA’s are envisaged, but a different format is not excluded.
A first meeting of the task force preparing these proposals took place at CERN on Oct 30. A brief summary of the state of each follows
Presentations from the three coordinators will be presented at CARE06 on Thu Nov 16 afternoon.
IA1- European proton accelerator R&D
         R. Garoby is coordinating the preparation of this proposal. The general theme is proton accelerator R&D, strengthening LHC
and the CERN p complex. The total cost of related LOIs is well above 60 M, a reasonable goal is applying for 15 M from EU, with 45 M
as total budget. Activities relevant for future neutrino beams would take place in the high power proton driver sector (a JRA being
proposed in this area under the responsability of Garoby and collaborators). M. Zito/CEA and J. Pozimski /RAL and others will follow
this for BENE exploring also opportunities in the sector of Rapid Cycling Synchrothrons for neutrino applications (NB we need them to
be truly rapid, 50 Hz eventually, and therefore NC!).) and target sector (where a WP on high power targetry & collection can be envisaged
within a JRA on high power and radiation deposition in materials, chiefly motivated by the R&D for a high quality collimators for LHC).
C. Densham/RAL and M. Dracos/IN2P3 have taken the charge of establishing contacts with all EU experts, in and out of the particle physics
community, in particular the CERN CNGS and ISOLDE experts, and to try to define the content of such a WP. CARE06 in Frascati should
help these contacts. A Networking Activity (NA) containing a fraction of BENE areas of interest could be accommodated in this IA.
Transnational Access options have not yet been seriously considered yet.
IA2-Novel accelerating techniques
       E. Jensen is coordinating the preparation of this proposal. This is much less advanced than IA1
       The total cost of related LOIs is 85 M. It has to be reduced dramatically. The leitmotif of the IA is strenghtening CTF3.
       But strengthening "our" new RAL muon facility could be part of it too. A MICE JRA is being prepared by K. Kyberd and A. Blondel.
       A JRA on FFAG’s appears negotiable, if downsized. Francois Meot (IN2P3/CEA) has accepted the task, in collaboration with R. Edgecock,
      S. Machida and other experts of pushing this within the team preparing this IA proposal.
       Discussion at CARE06 should prove very instrumental.
       No discussion on any Networking Activity (NA) or Transnational Access has yet taken place in this IA.
IA3 Superconducting RF (SCRF) accelerators R&D:
       O. Napoly is coordinating the preparation of this proposal. This is also less advanced than IA1.
       The total cost of related LOIs is 31 M, with more big ones still coming. One is a JRA for a big RF testing facility.
              CARE06, 17 Nov 2006                                                                   V. Palladino Report on BENE Activities
       A JRA on 200 Mhz muon acceleration cavities could be accommodated in this. R&D on p acceleration cavity may instead go to WG1, will see

    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 possible
               becoming a polished BENE Interim Report
       • Design Study road traced by ISS


in spite of outstanding difficulties
   smaller size of our community & its core of active people
   CERN contribution being resurrected only now (very slowly)
   richness of options that makes consensus more laborious
                  NB legitimate different scientific interests do exist
   collapse       of FP6 calls                                       and more

Two main physics strategies
 use of the high neutrino rate (>1020/year) and energy (10-50 GeV) of
     Neutrino Factory + LMD (“Hyper-MINOS”)
      m  νe + νm     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 (“Hyper-Kamioka”)
      b  νe       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)
   p  νm                                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

Esample of comparison of physics reach: θ13 and CP violating phase

                                                  Figure 7 : 99%CL d 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(Dm2)=-1.
                                                  Sensitivities are compared with a 50 GeV Neutrino
                                                  Factory      producing    2×1020m    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)
     CARE06, 17 Nov 2006         V. Palladino Report on BENE Activities
                         A general remark
  Betabeam + Megaton                       and                     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                         !
                   we must push both very actively
                 catch opportunities wherever they emerge
seriously aim at building one in Europe in the “construction window”


   CARE06, 17 Nov 2006                    V. Palladino Report on BENE Activities
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

                                V. Palladino Report on BENE Activities an option
      The MERIT ( nTof 11) experiment

(US, Japan, CERN&RAL)
             holds the key to any superbeam !!!
               tests the single shot behavior at MMW driver
                     of target and collection (solenoid, horn?)

              can we master the MMW?
  should make that more known
                   better supported and manned

  should evolve that into a MMW target and collector Test Area?
 The most crucial experiment for the
           future of the ν

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
                                    will no doubt greatly help
                                               a few fractions of FTE can make an impact
