Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS positive signals, after meager years of LHC crisis 1) EU approval (HIPPI and BENE) Main conclusion MMW and ’s  back 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

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS 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)

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS Third conclusion …. a question LHC (& upgrade) will be the first priority Next HE project.. CLIC Will there be a window for a MMW investment?

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS Two main physics strategies use of the high neutrino rate (>10 20 /year) and energy (10-50 GeV) of Neutrino Factory + LMD detector of large but not huge mass ( Kt), necessarily magnetic (a dense magnetized Iron detector, or, possibly, Li-Argon), a few 1000 Km away. use of the lower neutrino rate ( /year) and energy (sub-GeV) of Betabeam + Megaton low density detector of very large mass (0.5-1 Mt) and volume (0.5-1 Mm 3 ) non magnetic (a Water Cerenkov detector, or possibly, again Li-Argon), a few 100 Km away.  ν e + ν    νe  νe

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS 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 ν e →ν μ in the first, ν μ →ν e. 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  ν

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS 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(  m 2 )=-1. Sensitivities are compared with a 50 GeV Neutrino Factory producing 2   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) !!!

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS Betabeam + MegatonNuFact + 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” ! !

Reunion GDRν, College de France,Paris,\20Oct05V. Palladino BENE and the ISS 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

Gschwendtner BENE is a Networking Activity (N3) in the framework of CARE (Coordinated Accelerator R&D in Europe).CARE 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.
