Description and objectives of the activity

The main objective of this Joint Research Activity is the improvement of nuclear tagging techniques. INTAG will be concerned with the development of instrumentation (separators and detectors) that is used to identify the radioactive nuclei with respect to their atomic number Z and mass number A. This is expected to increase the experimental peak-to-background ratio in specific cases by several orders of magnitude.
Expected outcome

The research project will impact on the use of the following major research instrumentation:
  • JUROGAM, SACRED, RITU, GREAT (Jyväskylä)
  • GASP, CLOVER-ARRAY, PRISMA, CAMEL (INFN Legnaro)
  • SPIRAL, EXOGAM, VAMOS, LISE (GANIL Caen)
  • SHIP, FRS, RISING (GSI Darmstadt)
  • HRS, REX, MINIBALL (ISOLDE CERN)
In each case the instrumentation is employed by the research infrastructure to accelerate radioactive ions (SPIRAL, REX), select them (RITU, GREAT, PRISMA, CAMEL, VAMOS, LISE, SHIP, FRS, HRS) or study the electromagnetic emission from the excited nuclei (JUROGAM, SACRED, GASP, CLOVER-ARRAY, EXOGAM, RISING, MINIBALL). Studies of nuclear structure far-from-stability are employing stable beam or radioactive ion beam accelerators. This JRA aims to improve the selection of nuclei, which is the key component of every experimental study. The instrumentation developments in INTAG will also benefit the proposed facilities at GANIL (SPIRAL2), INFN Legnaro (SPES), CERN (HIE-ISOLDE), FAIR, and EURISOL.
The outcome of all research and development within this project will be disseminated to the wider scientific community through conference reports and scientific publications. It is expected this output, which includes the results of testing of prototype equipment, will be used as the basis for research grant applications within the national funding agencies for major “next-generation” instrumentation. The major risk here will arise from fluctuations in national budgets that impact upon the success of grant bids. It is also anticipated that some of the technological developments (e.g.high detector granularity) will be available to disciplines outside of nuclear physics, e.g. medical applications such as PET.
The 8 task-group representatives and overall coordinator are members of the scientific coordination committee that meets annually to review scientific and technical progress. Four task-group representatives and overall coordinator are members of the management committee that meets annually to coordinate technical and financial reporting. Overall activity workshops are also held annually for the whole collaboration (note that all meetings are held at the same venue and period to minimize travelling). Ad hoc workshops are held for each task sub-project when as necessary, at least once per two and a half years per task.
