The International AGATA Collaboration will meet in Milan for the 24th AGATA Week and the AGATA Collaboration Council from September 9th to 13th, in the classrooms of the University of Milan at via Valvassori Peroni 21, as well as at the Department of Physics and the INFN Section. This will be an opportunity to discuss the latest technological developments and scientific activities related to the AGATA spectrometer, the most sophisticated instrument in the world for gamma-ray detection, built with significant participation from nuclear physicists in Milan. The Milan group specializing in nuclear physics and gamma-ray spectroscopy holds key roles in the construction and operation of the apparatus and in promoting and conducting the physics campaigns with AGATA.
The meetings will be attended by representatives from the main European funding agencies, local authorities, and numerous members of the AGATA collaboration, as well as by a large representation of students and young researchers. AGATA is based on segmented hyper-pure germanium crystals and is an innovative modular detection apparatus that, in its final version, will consist of 180 crystals organized into triple clusters.
AGATA offers the possibility to explore the structure of exotic nuclei with unparalleled efficiency and sensitivity. These nuclei drive reactions in stars and are produced in the laboratory through collisions between stable and radioactive ions. This technological gem is the result of a European collaboration involving 13 countries and 40 research institutes, with Italy being one of the major contributors through the GAMMA group of the National Scientific Commission for Nuclear Physics of INFN. The scientific adventure of AGATA began at the Legnaro National Laboratories in 2010. At that time, the so-called AGATA Demonstrator, consisting of the first five triple clusters, demonstrated the exceptional characteristics of this revolutionary instrument through a series of pioneering experiments with stable beams. AGATA subsequently operated at the GSI Laboratory in Germany (2012-2014) and at GANIL in France (2015-2021), using reactions with exotic beams and gradually increasing the number of detectors. AGATA’s return to Legnaro marks the beginning of phase 2 of the apparatus construction. In Legnaro, AGATA will cover half of the solid angle and conduct measurements with the large acceptance PRISMA magnetic mass spectrometer, and with complementary instruments for detecting charged particles, neutrons, and high-energy gamma rays, using both intense stable ion beams provided by the Tandem-ALPI-PIAVE accelerator complex, and radioactive beams produced by the SPES facility.
