  14. MUST2 + TIARA Testing Instrumentation Concepts for EURISOL Task 10 : Physics and Instrumentation Robert Page

  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

  20. 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

  21. 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

  22. 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
