NEW DETECTORS FOR SPIRAL 2Remark: The detectors for the experiments at SPIRAL 2 are not

included today in the SPIRAL2 budget. Other sources of money (ANR, AP IN2P3, GANIL, International

Collaborations) should be found Typically, for the existing detectors at GANIL France contributes more

than 40%

• Instrumentation for experiments with low energy beams• Separator/Spectrometer for high intensity stable beams • FAZIA - dynamics array (collaboration just formed officially)• Active targets• AGATA (Demonstrator and full array)• Neutron array(s) (reaction studies, in-beam & decay spectroscopy)• Scintillator-based gamma array• Modifications of the existing detectors

– VAMOS, TIARA, MUST2,…
