  1. 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! Marco Zito

  2. 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! Marco Zito

  3. What Euroν 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 Marco Zito

  4. What Euroν 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 CDR’s Marco Zito

  5. 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 Marco Zito

  10. 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. Marco Zito

  11. Collectors M. Dracos horns In operation In operation completed Or solenoid (SB) built MiniBooNE Marco Zito NUMI CNGS K2K

  12. Focusing system: magnetic horn M. Dracos Current of 300 kA p To decay channel Protons B = 0 Hg Target B1/R Marco Zito

  13. Horn prototype ready for tests M. Dracos Marco Zito

  14. The power supply M. Dracos Due to the high price go to a modular system and increase small by small the current Marco Zito

  15. 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 Marco Zito

  16. "Physics" studies to be restarted M. Dracos P (kW) corne 2 z (cm) energy deposition z (cm) corne Marco Zito

  19. Milestones Marco Zito

  20. Conclusions • SuperBeam work package of the Euroν DS is focusing on the key issues for this project • The SPL to Fréjus project is the baseline • Excellent news from SPL side • Feasibility and conceptual solutions for the target and collector (horn) will be studied • A strong European collaboration is ready to contribute to this field Marco Zito
