GODDESS and the ORRUBA arrays for ReA and Fast Beams at FRIB
ORAL
Abstract
The Facility for Rare Isotope Beams (FRIB) will give unprecedented access to fast and reaccelerated beams of exotic nuclei with intensities and energies appropriate for direct reaction studies. The large-solid-angle, highly segmented ORRUBA and superORRUBA silicon detector arrays routinely operate at the NSCL/FRIB for both fast beam and reaccelerated beam experiments, and are anticipated to continue at FRIB. The deployment of these detectors is enhanced by coupling to GRETINA/GRETA in a system known as GODDESS, which will provide a ~4pi particle gamma spectrometer with mm spatial resolution and semiconductor energy resolution. superORRUBA is routinely coupled to the JENSA gas-jet target for direct reaction studies with ReA3 beams. These systems also include fast ionization chambers for beam/recoil measurement. An overview of the instrumentation and some of the physics interest will be discussed.
