AGATA (gamma-ray detector)

A schematic view of the AGATA array in the full 4π configuration

AGATA, for Advanced GAmma Tracking Array, is a High-Purity Germanium (HPGe) semiconductor detector array for γ-ray spectroscopy that is based on the novel γ-ray tracking concept.[1] It offers excellent position resolution thanks to high segmentation of individual HPGe crystals and refined pulse-shape analysis algorithms, and high detection efficiency and peak-to-total ratio thanks to elimination of Compton-suppression shielding in favour of tracking the path of γ rays through the spectrometer as they are scattered from one HPGe crystal to another. AGATA is being built and operated by a collaboration including 40 research institutions from thirteen countries in Europe.[2] The first Memorandum of Understanding for the construction of AGATA has been signed in 2003 by the participating institutions; the updated Memorandum of Understanding, signed in 2021, foresees the extension of the array to a 3π configuration by 2030. Over the years, AGATA has been steadily growing, and currently is operated in a 1π configuration at Legnaro National Laboratories after campaigns at GANIL (2014-2021), GSI Helmholtz Centre for Heavy Ion Research (2012-2014) and Legnaro National Laboratories (2010-2011).[3] AGATA can be coupled with ancillary detectors, such as magnetic spectrometers, fast-timing detectors, charged particles or neutron detectors.
