GRETINA is the most sensitive gamma-ray detector ever built for studies of the nucleus, including how the natural elements were made in stars and supernovae, and the properties of artificial superheavy elements. GRETINA, now being assembled at Berkeley Lab's 88-Inch Cyclotron, is the first stage of GRETA, the even more powerful Gamma-Ray Energy Tracking Array.
