Description
The Gamma-Ray Energy Tracking Array (GRETA) Project started in 2017, following nearly a decade of successful science with the predecessor GRETINA array. Led by the Nuclear Science Division at LBNL, and with a team including scientists, engineers and technical staff from NSD, Engineering, and ESnet, as well as from partner institutions ANL, ORNL and FRIB, GRETA recently completed the CD-E-4A milestone, marking the completion of construction and initial commissioning of all technical systems (mechanical, electronics and computing) with a subset of Quad Detector modules. It is currently being installed at the Facility for Rare Isotope Beams (FRIB), with first science measurements expected at the end of 2026. I will review the GRETA project, both scientific and technical aspects, and the progression toward anticipated first science at FRIB.
