The Gamma-Ray Energy Tracking Array has completed its commissioning and characterization run at the Facility for Rare Isotope Beams. The spectrometer uses high-purity germanium detectors to observe atomic nuclei with increased precision. This milestone confirms the system is operational and ready to begin its scheduled research experiments at the facility.

This technology allows scientists to track gamma rays emitted by rare isotopes to better understand nuclear structure and behavior. The data collected will refine theoretical models of the atomic nucleus, which are used to support advancements in energy production, national security, and medical applications. These improved models provide a foundation for future developments across the broader nuclear science sector.

After a successful commissioning run, GRETA is ready to give researchers an unprecedented look into the hearts of atoms.

The Gamma-Ray Energy Tracking Array (GRETA), the world's most advanced gamma-ray spectrometer for nuclear science, has taken first beam and successfully completed a commissioning and characterization run at the Facility for Rare Isotope Beams (FRIB) at Michigan State University. The milestone confirms the detector is performing as anticipated, giving researchers a way to observe atomic nuclei in greater detail than ever before.
