Spoke cavities development _at_ IPN Orsay

• 2 prototypes at ?0.15 and ?0.35 fabricated and
  successfully tested at 4.2 K.
• This technology is the basis for the 3-Spoke
  required by the Driver linac

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 RD 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 gtgt 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

Organization of the EURISOL Collaboration

• Collaboration board representing participants gtgt
  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

22
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

23
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
