  1. Beta Beam Design Study as part of EURISOL Outline • EURISOL Design Study • Beta Beam Conceptual Design • Synergies with EURISOL • Beta Beam Work Units • Preliminary Planning • Conclusions Michael Benedikt, AB Division, CERN EURISOL - Beta Beam Design Study

  2. The Beta Beam in EURISOL • EURISOL design study writing committee • Graziano Fortuna (INFN-LNL, study coordinator), Peter Butler (CERN) and Yorick Blumenfeld (Orsay). • Mats Lindroos, special consultant for the beta-beam. • EURISOL study • Organised in 12 “Tasks” of which one is the beta-beam aspects. • Beta Beam task coordinator Michael Benedikt (CERN) • Key-dates • 2nd week of January 2004, second draft from task coordinators. • 26 January 2004: final meeting EURISOL steering committee and design study writing committee. • Beginning of February 2004: final version proposed by the writing committee. • 16th February 2004: final meeting with task coordinators. • 4 March 2004: design study proposal submitted to EU. EURISOL - Beta Beam Design Study

  3. Eurisol Design Study Tasks • Preparatory meeting for EURISOL design study proposal14. Nov in Orsay. • First drafts presented by task coordinators. • Proton Accelerator (Alberto Facco, INFN-LNL)  • Heavy-Ion Accelerator (MH. Moscatello, GANIL) • Cryomodule Development (S. Bousson, IPNO) • Direct Target/Ion Source (J. Lettry, CERN) • Solid Converter-Target/Ion Source (L. Tecchio, INFN-LNL) • Liquid-Metal Target/Ion Source (F.

Schmidt, GSI) • Beta-Beam Aspects (M. Benedikt, CERN) • Co-ordination and Layout (Not yet allocated) EURISOL - Beta Beam Design Study

  4. Beta Beam Concept Design AIM: provide beams of electron (anti) neutrinos by decay of beta active ions. Experiment Proton Driver SPL Acceleration to final energy PS & SPS Ion production ISOL target & Ion source SPS Beam preparation ECR pulsed Neutrino Source Decay Ring Decay ring Br = 1500 Tm B = 5 T C = 7000 m Lss = 2500 m 6He: g = 150 18Ne: g = 60 Ion acceleration Linac PS Acceleration to medium energy Bunching ring and RCS EURISOL - Beta Beam Design Study

  5. Task: Beta Beam Aspects Starts at exit of heavy ion LINAC (~100 MeV/u) to Decay Ring (~100 GeV/u). Experiment Proton Driver SPL Acceleration to final energy PS & SPS Ion production ISOL target & Ion source SPS Beam preparation ECR pulsed Neutrino Source Decay Ring Decay ring Br = 1500 Tm B = 5 T C = 7000 m Lss = 2500 m 6He: g = 150 18Ne: g = 60 Ion acceleration Linac PS Acceleration to medium energy Bunching ring and RCS EURISOL - Beta Beam Design Study

  6. Strongly linked Tasks • High power proton driver  TASK: Proton Accelerator. • 5 MW – 5mA CW superconducting proton linac. • Ion production (Ne)  TASK: Direct Target & Ion Source. • 100 kW target station. • Ion production (He)  TASK: Solid Converter-Target/Ion Source. • 100 kW target station. • Pulsed ECR source  TASK: Beam Preparation. • 60 GHz pulsed source to give time structure. • Ion acceleration  TASK: Heavy Ion Accelerator. • Acceleration to ~100 MeV/n • Radiation aspects  TASK:Safety & Radioprotection. • General radioprotection aspects, does not include collimation system(s). • Physics case  TASK:Physics & Instrumentation. • Low energy Beta Beam physics case and potential use of (parts of) beta beam complex for nuclear physics. • High energy Beta Beam physics case is not included in any task! EURISOL - Beta Beam Design Study

  7. Beta Beam Work Units • Low energy ring(s) design (bunching & low energy acceleration). • Acceleration in PS and SPS (HW modifs, acceleration schemes, “new PS”). • Decay ring design + transfer lines. Major activities • Transverse and longitudinal beam dynamics. • Radiation protection, machine protection, collimation. • Magnet and RF engineering. • Instrumentation. • Power converters. • Vacuum. • Technical infrastructure. • (Control system should be addressed later to use newest technology). EURISOL - Beta Beam Design Study

  8. Preliminary Planning (I) • 0 – 6 months: • Define working areas and links with other EURISOL tasks. • Refine and improve base line scenario. • Consistent parameter list (physics, other tasks). • Final choice of base line design. • 6 – 24 (18) months: • Optics design of low energy rings, decay ring and TL. • Beam dynamics simulations along complete chain with PS, SPS. • Basic scheme for machine protection • Identification of critical processes (beam dynamics) • Identification of critical hardware components. • Preparation of intermediate report. EURISOL - Beta Beam Design Study

  9. Preliminary Planning (II) • 18 (24) – 36 months: • Final optimisation & refinement of beam dynamics and optics. • General layout and technical design work. • Technical design of critical components. • 36 – 48 months: • Preparation of Beta Beam Complex technical design (including technical infrastructure, cost estimate, time estimate). • Preparation of final report.

  10. Manpower Requirements • Manpower will be needed in sequential order, not parallel. • The manpower requirement does not include beta beam related activities in other Eurisol Design Study Tasks! EURISOL - Beta Beam Design Study

  11. Prototyping Work • At present there is no prototyping work foreseen within the Beta Beam Task. • Beta Beam related prototyping work is foreseen in the EURISOL task “Beam Preparation” (A. Jokinen). • Development of 60 GHz pulsed ECR source (Pascal Sortais et al. LPSC-Grenoble) Travel Budget • Estimated travel budget requirements: 40 k€/year EURISOL - Beta Beam Design Study

  12. Potential Partner Institutes • CEA, France • CERN, Switzerland • GSI, Germany • IN2P3, France • INFN, Italy • RAL, UK • TRIUMF, Canada Next Steps • Contact all colleagues that have shown interest to participate to the Beta Beam task. • First task group meeting to prepare Beta Beam task proposal: Wednesday, 14. January 2004. EURISOL - Beta Beam Design Study

  13. Conclusions • Beta Beam design study is well integrated in the EURISOL design study. • Strong synergies between Beta Beam and several other EURISOL tasks. • Good progress is made but final planning and proposition can only be made after discussions between participants of Beta Beam task and related tasks.
