The study of atomic nuclei – their structure and reactions – directly relates to fundamental questions in physics, such as understanding the origin of the elements and how complex many-body quantum systems organize. Much of what we know about nuclei comes from the measurement and characterization of their energy level schemes, and many experimental tools and techniques have been developed to aid these studies. Among them, high-resolution γ-ray spectroscopy has proven to be one of the most powerful, and γ-ray spectrometers play a central and vital role in nuclear science.  Planned as a key instrument in this field the Gamma-Ray Energy Tracking Array (GRETA) is the realization of a full 4π γ-ray tracking detector, capable of reconstructing the energy and three-dimensional position of γ-ray interactions within a compact sphere of high-purity germanium crystals.The GRETA geometry is based on a dodecahedron with 12 regular pentagon and 120 irregular hexagons with two unique shapes that tile the geodesic sphere. Each GRETA Detector Module is geometrically identical and contains four hexagonal crystals housed together in a single cryostat.The primary function of the Detector Array Sphere is to position the 30 Detector Modules precisely in a spherical array surrounding the target position. The GRETA Detector Array Sphere will consist of two type hemispheres accommodating the Detector Modules, held in space by a multipoint support system. Each hemisphere will be made up of 3 parts allow both the forward and back sections to be removed for experimental configuration.The items and services eventually purchased for Lawrence Berkeley National Lab (“Berkeley Lab” or “LBNL”) will support the GRETA Project.You can learn more about GRETA and this project at the following web locations:
