EURISOL DS Major Technical Achievements Managerial achievements Proposals for the Future

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 132 Sn 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).

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 H-,D- H+,D+, 3 He ++ RFQ 176 MHz HWR 176 MHz 3-SPOKE 352 MHz Elliptical 704 MHz 4 MW H- 100 kW H+, 3 He MeV/u 60 MeV/q 140 MeV/q 1 GeV/q B stripper foil stripper >200 MeV/q D, A/q=2 =0.047 =0.03 =0.09 =0.15 =0.65 =

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

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 Design of the post-accelerator

Management Achievements Organization of mid-term review (April 2007) Organization of 3 rd 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 Mandate Written Production of brochure for General Public Defining strategy for the future of EURISOL

Financial Situation Second Pre-Financing has been received and distributed. Third expected next year (no auditing for 3 rd 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

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.

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

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

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

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 Startup should be in fall 2009
