Task 10 : Physics and Instrumentation
Robert Page
• EURISOL has a stable Design,
validated by worldwide experts
• During the final year, the work is
concentrated on prototype building
and testing
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
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,
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!
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
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
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
