15. EURISOL has a stable Design, validated by worldwide experts During the final year, the work is concentrated on prototype building and testing

16. Management Achievements EURISOL User Group: Angela Bonaccorso, chair. First workshop Jan. 2008; Charter established; election of executive committee: 27candidates for 8 seats, 354 voters. Site Investigation Panel : A. Shotter, G. Cuttone, D. Geesaman, A. Mueller, S. Myers. 3 meetings. Will report to steering committee in November Third annual report accepted for scientific part. Comments on financial part received last week. Review panels organized for MMW converter and post accelerator. Production of brochure for General Public Next Town Meeting March 30-April 1 2009 in Pisa. Defining strategy for the future of EURISOL

17. 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.

18. Role of the EURISOL Collaboration Follow the scientific and policy recommendations of NuPECC Promote and Coordinate the R&D to further EURISOL, including work at intermediate generation facilities 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 an engineering report for the facility Support the EURISOL User Group; organize Town Meetings Has been endorsed by NuPECC, thank you!

19. Multi-Community Design Study on High Power Targets : Neutrinos, Neutrons and Ions Establish limits for Liquid metal and solid target technology Study common infrastructure and collect data for licensing work Computer studies of cavitation and bubble development, determination of shock fronts and studies of the beam/pressure pulse Off-line studies at liquid metal target laboratories such as IPUL in Latvia, SNS in Oak Ridge and J-Parc in Tokai Beam tests to study cavitation and mitigation at high instantaneous beam intensity facilities such as ISOLDE and AGS In-beam tests at a high power facility of new concepts Under Discussion

21. Organization of the EURISOL Collaboration Collaboration board representing participants >> Elects collaboration chairperson and appoints project leader. Project office supported by a modest collaboration fee (~5000 E/year/lab). Engineering work coordinated by project leader and funded by funding agencies (+ other), preferably coordinated by NuPNET. Work divided into work packages

22. 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

23. 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
