In April, researchers from around the world gathered at LBNL for a two-day workshop and dedication event to celebrate the completion of the construction of GRETA (Gamma Ray Energy Tracking Array).  GRETA, which was conceived of almost thirty years ago at LBNL will be the world’s most sensitive gamma-ray spectrometer and will soon be a key instrument at the Facility for Rare Isotope Beams (FRIB) at Michigan State University.  The GRETA project is scheduled for Phase-I completion this summer.

The workshop featured presentations on GRETA, the evolution of gamma-ray spectroscopy, and aspects of nuclear structure physics.  The dedication event included speeches from GRETA Project Director and NSD Sr. Scientist Paul Fallon, LBNL’s Deputy Director for Research Carol Burns, and representatives from DOE NP, a “ribbon cutting” ceremony (see figure), and a reception.  Attendees at the event included individuals who were key to the inception of GRETA, and its development and realization over the last three decades.
