The Gamma-Ray Energy Tracking Array (GRETA), which is installed at the Facility for Rare Isotope Beams (FRIB) at Michigan State University, has successfully completed a commissioning and characterization run, establishing that it is ready for scientific operations.

According to Lawrence Berkeley National Laboratory, which made the announcement, the measurements that scientists make with GRETA will improve the theoretical models of the atomic nucleus that underpin research in nuclear physics, astrophysics, energy, medicine, and national security.

Researchers announced earlier this month that they have completed major construction of the Gamma-Ray Energy Tracking Array (GRETA), a precision tool for gamma ray spectroscopy that, according to Paul Fallon, a researcher at University of California–Berkeley and GRETA’s project director, will be 10 to 100 times more sensitive than previous nuclear science experiments. Fallon was quoted in an August 8 article published by Lawrence Berkeley National Laboratory (Berkeley Lab)—where GRETA’s project leaders are based and GRETA was assembled.
