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
(task 6)
•
Investigate technologies for the instrumentation of the future (task 10)
•
Provide a conceptual study for a beta-beam neutrino facility (task 12).

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
EURISOL parallel cw Proton extraction
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

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 Preconstruction 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 EURISOL 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
