- The Advanced Gamma Ray Tracking Array AGATA C. Rossi Alvarez Física, Astronomía y Matemáticas New accelerator facilities for radioactive-ion beams and high-intensity stable beams will start operation in afew years. Although these beams will provide interesting opportunities for exploring unknown territories ofthe nuclear landscape, the experimental conditions will be very challenging and, indeed, the nuclear structurecommunity has realized that a new generation of powerful arrays for °ray spectroscopy has to be built inorder to cope with them. As a result of years of experience with Compton suppressed germanium arrays andof intensive R&D work targeted to extend their limits, it is now clear that the next 4¼ °ray spectrometers willbe built fully from germanium detectors and will be based on the technique of °ray tracking. The AdvancedGAmma Tracking Array (AGATA), proposed in Europe, will be an instrument of major importance for nuclearstructure studies at the very limits of nuclear stability. It will be built out of 120/180 highly segmented Gecrystals operated in position sensitive mode by means of digital data techniques and pulse shape analysis of thesegment signals. AGATA will be able to measure ° radiation in a large energy range (from » 10 keV to » 10MeV), with the largest possible photopeak efficiency (25 % at M° = 30) and with a good spectral response.In particular, its very good Doppler correction and background rejection capabilities will allow to performstandard °ray spectroscopy experiments using fragmentation beams with sources moving at velocities up to¯ » 0:5. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434578 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34
