Main goals of CARINA network

• carry out mapping studies of European situation
  concerning projects, facilities, and teams to
  identify available instrumentation and human
  potential
• develop research capabilities of existing Large
  Scale Facilities (LSF) and smaller laboratories /
  enhance involvement in the future RIB facilities
• record needs for new instrumentation and
  techniques / look for existing solutions in
  other fields
• coordinate research efforts by defining and
  proposing common research goals and by
  encouraging new collaborations and new RD
  projects

CARINA activities

• Two CARINA workshops organized
• First workshop Perspectives in European Nuclear
  Astrophysics, Parador dAiguablava, Girona,
  Spain, June 8th - 10th, 2005
• 39 participants from ten countries
• five review talks on astrophysical models
  (explosive burning and AGB/quiescent burning),
  nuclear models for astrophysics, experiments with
  RIB at LSF, and experiments at small facilities
• short talks and discussions in working group
  sessions (plenary)
• summary of the conclusions
• large variety of problems needs large variety of
  methods
• specific tools needed for different
  nucleosynthesis scenarios
• small-scale facilities as feeders to
  large-scale facilities
• establish a flagship ISOL-type facility for
  nuclear astrophysics with gas targets, recoil
  separator, spectrometer, solid-state detectors,
  and g-ray detection systems available
• find tentative lists of astrophysical sites and
  nuclear models for nuclear astrophysics

CARINA activities

• Second workshop Frontier Research in European
  Nuclear Astrophysics, Spaulomont, Spa, Belgium,
  April 25th - 28th, 2007
• 37 participants from 13 countries
• 21 talks and five discussions (plenary)
• workshop explored opportunities for new European
  facilities
• agreement that additional facilities,
  specifically for nuclear astrophysics, are
  warranted and needed
• lively discussion over strategy should it be a
  dedicated nuclear astrophysics proposal, or
  complementary to a general nuclear physics
  proposal?
• possibilities include nuclear astrophysics labs
  network, an underground accelerator, a dedicated
  nuclear astrophysics separator for capture
  reactions, reclamation of radioisotopes, ...

CARINA activities

• Three collaborations established
• EURISOL task 10 Physics and Instrumentation -
  Astrophysics since January 2006
• CARINA coordinator is leader of EURISOL subtask
• combine efforts to develop high-intense,
  low-energy, and pure unstable beams suited for
  experiments on nuclear astrophysics
• distribution of beam-time ? experiments on
  nuclear astrophysics very time-consuming due to
  low cross sections
• examples of key reactions in Novae
  nucleosynthesis18F(p,a)15O, 25Al(p,g)26Si,
  30P(p,g)31S, 17O(p,g)18F, 17O(p,a)14N, ... ?
  beams of 18F, 25Al, 30P, and 17O with intensities
  higher than109 pps and energies below 500 keV
  (cms) requested
• r-process nucleosynthesise.g. n separation
  energies, masses, b-decay half-lives, fission
  branchings and products, b-delayed n-emission
  branchings, ...

CARINA activities

• ECOS (European COllaboration on high intensity
  Stable beams)
• support efforts to construct high-intensity
  stable heavy-ion beam facility and high-current,
  low-energy accelerator lab in Europe
• CARINA-JINA Collaboration on Nuclear Data
  Compilations for Nucleosynthesis Modelling
• develop updated and unified nuclear database for
  stellar nucleosynthesis modelling
• update and merge presently most important data
  libraries for astrophysics (e.g. KADoNiS, NACRE,
  REACLIB)
• first collaboration meetingNuclear Physics
  Data Compilation for Nucleosynthesis Modelling,
  Trento, Italy, May 29th - June 1st, 2007
• second collaboration meeting planned for spring
  2008

Future projects

• JRA9 RIB4NAjoint research activity on
  development, production and acceleration of
  radioactive ion beams
• NA16 ENNAnetwork on experimental and
  theoretical nuclear astrophysics
