2. EURISOL DS • Major Technical Achievements • Managerial achievements • Proposals for the Future

4. The Main Challenges • Design a 5MW; 1GeV proton driver with additional capability of 200 AMeV deuterons and A/Q=2 Heavy Ions (Task7) ; build and test prototypes of the cavities (task 8). • Design a liquid Hg converter which will accept 5 MW of beam power (task 2). • Design a UCx target which will make the most efficient use of the neutrons produced (task 4). • Evaluate the safety constraints of the above set up (task 5). • Design an efficient multi-user beam distribution system (task 9). • Design a superconducting HI LINAC capable of accelerating 132Sn up to 150 AMeV (task 6) • Investigate technologies for the instrumentation of the future (task 10) • Provide a conceptual study for a beta-beam neutrino facility (task 12).

5. New baseline scheme with extended capabilities • 2 injection lines for H,D, He and A/q=2 ions • SARAF scheme up to 60 MeV/q • IPNO scheme from 60 to 140 MeV/q • CEA scheme from 140 to 1000 MeV/u • cw beam splitting at 1 GeV (1 line 4 MW + 3 lines 100 kW) • Total length of the linac: ~240 m 4 MW H- B stripper Elliptical 704 MHz 1 GeV/q RFQ 176 MHz HWR 176 MHz 3-SPOKE 352 MHz H-,D- 100 kW H+, 3He2+ =0.09 =0.15 =0.03 =0.047 =0.65 =0.78 H+,D+, 3He++ 1.5 MeV/u foil stripper 60 MeV/q 140 MeV/q >200 MeV/q D, A/q=2 10 36 31 63 97

6. EURISOL parallel cw Proton extraction 1 GeV Multiple Extraction • 3 splitting stations • 4 simultaneous users for cw proton beams: • 1  4 MW • 3  0100 kW (continuously adjustable) • Unique ability of EURISOL at present

7. Design of the post-accelerator SPIRAL-2 philosophy:Smoothest beam dynamics (regular FDO lattice, low number of -sections), Modular solution and simple cryostats, Separated vacuum (safety with FP), Warm focusing (easier for alignement), Possibility to insert diagnostics at each period, ease of tuning Main technical requirements: Only 2-gap cavities (high q/A acceptance) Max. accelerating fields 7.8 MV/m Nominal operation for A/Q between 4 and 8

8. New Target Concept

9. Reactor Type Target Concept Validated by International Advisory Board

10. Double effusion line prototype(E. Bouquerel, L. Penescu) Bellows Cu body 2xwater cooled transfer lines 2x20cm containers RIB 2 pneumatic valves ISOLDE cold FEBIAD MK7Ion source Heat screen 1.4GeV protons

11. Conceptual design of 100kW target station • Underground target position • Front-end retracts vertically • Hot-cell for target exchange • Separator in 3rd level • Neighboring hot-cell accessible during run Effective dose rate maps Effective dose rate E (Sv/h) Soil activation!

12. Fragmentation of 132Sn (Preliminary results) Fragmentation of 132Sn on Be D. Perez and D. Dragosavac

13. Management Achievements • Organization of mid-term review (April 2007) • Organization of 3rd Town meeting in association with EURONS • Link with EC concerning financial aspects of annual report and extension of the contract to 31/07/2009 • Start up of EURISOL User Group: Angela Bonaccorso, chair. First workshop Jan. 2008; Charter established; election of executive committee (UEC) in progress • Start-up of Site Investigation Panel : A. Shotter, G. Cuttone, D. Geesaman, A. Mueller, S. Myers. First Meeting Jan. 2008. Mandate Written • Production of brochure for General Public • Defining strategy for the future of EURISOL

14. Financial Situation • Second Pre-Financing has been received and distributed. Third expected next year (no auditing for 3rd year). • Extension will allow the timely use of all resources • Spending in-line with expectations (95%) • Slight overspending in Personnel compensated by under spending in T&S and Consumables

15. Proposal for the Future of EURISOL • EURISOL has made use of EC instruments: 5th framework RTD and 6th framework DS. • Major advances have been achieved and a large community with varied technical expertise has developed and must continue to be nurtured • Full engineering report necessary before Pre-construction phase: No (evident) EC instrument for funding. • We (the EURISOL DS MB) propose to form a EURISOL collaboration consisting of laboratories interested in participating in the continuing effort.

16. Role of the EURISOL Collaboration • Follow the scientific and policy recommendations of NuPECC • Promote and Coordinate the R&D to further EURISOL • Solicit support of the funding agencies, in particular through the NuPNET Eranet, and explore other funding opportunities (EC, intercontinental…) • Interact with the EC >> entry on the ESFRI list. • Goal : Produce a full engineering report for the facility

17. Organization of the EURISOL Collaboration • Collaboration board representing participants >> Elects collaboration chairperson and appoints project leader. • Project office supported by collaboration fee. • Engineering work coordinated by project leader and funded by funding agencies (+ other), preferably coordinated by NuPNET. • Work divided into work packages

18. EURISOL Work Packages (3-5 years) • Management (Project Office) • RIB production: Specific prototyping and tests • Neutron converter in beam • Fission target in n flux • New target materials; liquid metal direct target • Novel beam splitter system… • Prototyping at “intermediate” facilities; linked to EUR-ISOL Net in ENSAR • Documentation and licensing • Infrastructure • Updating the science case : coordinated by EURISOL User group

19. Requests • Very approximate price tag: 2M€/year for 4 years. • We would like the support of NuPECC to implement this plan (and welcome your suggestions). • Collaboration launched by the EURISOL Steering Committee in Nov. 2008 • Startup should be in fall 2009
