Description
In early summer 2012, the Gamma-Ray Energy TRAcking In-beam Nuclear Array GRETINA was installed in front of the S800 Magnetic Spectrograph for in-flight gamma-ray spectroscopy campaign with fast beams of rare isotopes. In this type of experiments rare-isotopes beams provided by the Coupled Cyclotron Facility of the National Superconducting Cyclotron Laboratory (NSLC) are delivered onto a reaction target placed at the center of GRETINA. Reaction residues are detected
in the spectrograph in coincidence with gamma rays in GRETINA. The high spatial resolution of GRETINA allows to perform accurate Doppler-shift reconstruction of the gamma-ray energies emitted by the reaction residues moving at velocities
typically exceeding 30% of the speed of light. GRETINA's tracking capability enables to acquire gamma-ray data of high spectral quality. More than 20 experiments have been performed covering topics in nuclear structure and nuclear astrophysics. This presentation will summarize the performance of GRETINA in this powerful configuration for fast beam spectroscopy and give
an overview on the physics program accomplished in this campaign.
