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 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).

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

1 GeV Multiple Extraction•3 splitting stations•4 simultaneous users for cw proton beams:

•1 4 MW•3 0100 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 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

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

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. 2008

• Startup should be in fall 2009
