Developments and prospects for GODDESS at FRIB
ORAL
Abstract
GODDESS is a coupling of an upgraded version of the highly-segmented silicon detector array ORRUBA (Oak Ridge Rutgers University Barrel Array) to the large HPGe detector arrays currently in operation the US. The commissioning campaign in 2015 employed Gammasphere for a series of stable-beam experiments; in early 2019, the system has been deployed with GRETINA for a campaign of measurements using stable, re-accelerated and in-flight radioactive beams at ATLAS at ANL for understanding nova and r-process nucleosynthesis. For this campaign, the instrumentation for GODDESS has been upgraded, along with a set of new beam detectors. These provide event-by-event particle identification and tracking of beam-like particles, critical for both the analysis of the experiments as well as real-time diagnostics for tuning radioactive beams. In parallel to these developments, ORRUBA has recently been coupled to the S800 at the NSCL for fast beam experiments with r-process nuclei. A brief summary of the upgrades, and prospects for deployment with GRETA for experiments at FRIB will be presented.
