1. EuroNu CERN February 5, 2008 Marco Zito Super-Beam work package Marco Zito Dapnia-Saclay On behalf of the SB w2 team EuroNu 5/2/2008 Thanks to M. Dracos for providing materials!

2. EuroNu CERN February 5, 2008 Marco Zito Outline About this workpackage Focusing on the most challenging/crucial problems : –The target - talk by C. Densham –The collector –The target/collector integration –Neutrino beam simulation Participating institutes: IN2P3, CEA/IRFU(previously Dapnia), CCLRC, Cracow U. of Technology Deliverables and milestones -> a CDR for the Superbeam!

3. EuroNu CERN February 5, 2008 Marco Zito What Euro ν DS Superbeam is about-1 Consider as baseline the SPL to Frejus concept MEMPHYS Far detector feasibility, excavation, engineering is covered by the Laguna DS

4. EuroNu CERN February 5, 2008 Marco Zito What Euro ν DS Superbeam is about-2 Proton driver and target : many issues in common between Super-Beam and NF Decide to join forces and tackle these problems in this WP The NF WP will focus on the muon front-end The conclusion of this WP will then be incorporated in the SB and NF CDRs

5. EuroNu CERN February 5, 2008 Marco Zito SPL Important and very positive recent news (see next slides from R. Garoby and F. Gerigk) CDR for SPL available Ongoing work by dedicated team Refinements, R/D, further studies in other frameworks (HIPPI, IA …) Changes to this proton-driver design only from the optimization of the target and collection or from the physics and detector studies

10. EuroNu CERN February 5, 2008 Marco Zito Collector Main challenges: design of a high current pulsed power supply (300 kA/100 μs/50 Hz), cooling system in order to maintain the integrity of the horn despite of the heat amount generated by the energy deposition of the secondary particles provided by the impact of the primary proton beam onto the target, definition of the radiation tolerance, integration of the target.

14. EuroNu CERN February 5, 2008 Marco Zito The power supply Due to the high price go to a modular system and increase small by small the current M. Dracos

15. EuroNu CERN February 5, 2008 Marco Zito Neutrino Beam simulation Needed to optimize the target, collector, decay tunnel Use modern tools (GEANT 4) and recent data (HARP) Input to the physics work package for the performance evaluation Need to develop in synergy with similar studies in existing SB and in the IDS community
