  1. NA10-NACTAR Network for Active Targets 12 institutions (France, Spain, UK, Germany, Poland) GANIL, France CENBG Bordeaux, France SPhN/DAPNIA/DSM Saclay, France IPN Orsay, France Subatech Nantes, France University Santiago de Compostela Spain University Liverpool UK Daresbury Laboratory, CCLRC, UK University of York, UK University of Birmingham, UK GSI Darmstadt Germany Krakow, Poland

  2. NA10-NACTAR A short word of history: R&D within FP6 Eurons JRA-01 ACTAR: Definition of best options for the realisation of active target detector concepts for exotic nuclei studies Future: CONSTRUCTION of detectorS….. Broad physics program: — two proton radioactivity — resonant elastic scattering — reactions of nuclear astrophysics interest — direct reactions at low energy (SPIRAL/SPIRAL2): inelastic scattering transfer rections, charge exchange reactions — studies of cluster states…. — elastic scattering at high energy (GSI/FAIR)

  3. NA10-NACTAR Several detectors will be constructed : different geometries (cubic, cylindrical) Different sizes (low energy/high energy), magnetic field or not… The detector tanks may be different but many common points Need for coordination, common effort, repartition of tasks: — theoretical support: IPN Orsay — Simulation package: Santiago de Compostela, GANIL, Nantes — Ray tracing algorithms: CENBG Bordeaux, GANIL — Gas handling system: GANIL — Read out chamber: CENBG, IPN Orsay, Saclay — Electronics: Saclay, Liverpool, Daresbury — Control&Command, Acquisition system: GANIL…

  4. NA10-NACTAR COLLABORATION — common meetings: progress reports on different activities, definition of priorities, definition of test procedures at the different stages of material delivery…, —organization of workshops (annual basis) on physics and technical issues — common Letters of Intent: LoI SPIRAL2, R3B — application for funds in the different countries — contacts with other equipments addressing the same physics case: EXL at GSI/FAIR, MUST2/GASPARD at GANIL/SPIRAL2

  5. NA10-NACTAR Active target detector : — innovative concept with high potential. — Proof of principle well established with MAYA and Bordeaux TPC for different physics programs. — Next generation of detector necessary to overcome present limitations —  « Niche » of experiments at different facilities (Resonance State in 7H, M. Caamano et al, PRL 99(2007)062502 First direct observation of two protons in the decay of 45Fe with a time projection chamber J.
