The AGATA projet is a European wide collaboration involving more than 44 institutions in 12 countries.
AGATA (Advanced GAmma-ray Tracking Array) is the next generation 4πγ multidetector array. The BGO anti-Compton shields, which occupy up to 50% solid angle in current arrays, are replaced by active germanium. To conserve a good peak to total it becomes necessary to track the photons in the detector. To achieve this, AGATA must be granular (this is why the Germanium crystals are segmented). One must also analyse the shape of the pulses generated by the photon interactions in the Germaniumm in order to determine the position and energy of the interaction points. Finally, one must be able to efficiently reconstruct the incident photon trajectories. With this γ tracking concept, the sensitivity of AGATA will be superior to any existing array by several orders of magnitude. It will be for a long time a rich source for nuclear structure physics providing the means for new discoveries and opening challenging new perspectives. In 2009, a demonstrator comprising 5 triple-clusters (a triple-cluster = 3 highly segmented detectors in one cryostat) was successfully commissionned at Legnaro. This commissioning stage was then followed in 2010 and 2011 by a series of physics experiments. AGATA is now being moved to GSI.
