“…A number of implant-decay correlation systems exist or are being planned for current and future fragmentation facilities including the beta-counting system at NSCL and eventually FRIB [438,439]; WAS3Abi [440] and CAITEN [441] at RIKEN; SIMBA at GSI [432]; the active stopper for the RISING campaign [442]; DESPEC AIDA at FAIR and at RIKEN [443]; and a system at Lanzhou [444]. The technique has also been implemented with gaseous detectors at a variety of facilities (see [445] for a recent example).…”

This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and electromagnetic radiation from radio to γ rays. The very red color of the associated kilonova suggests that neutron star mergers are an important r-process site. Astrophysical simulations of neutron star mergers and core collapse supernovae are making rapid progress. Detection of both, electron neutrinos and antineutrinos from the next galactic supernova will constrain the composition of neutrino-driven winds and provide unique nucleosynthesis information. Finally FRIB and other rare-isotope beam facilities will soon have dramatic new capabilities to synthesize many neutron-rich nuclei that are involved in the r-process. The new capabilities can significantly improve our understanding of the r-process and likely resolve one of the main outstanding problems in classical nuclear astrophysics.However, to make best use of the new experimental capabilities and to fully interpret the results, a great deal of infrastructure is needed in many related areas of astrophysics, astronomy, and nuclear theory. We will place these experiments in context by discussing astrophysical simulations and observations of r-process sites, observations of stellar abundances, galactic chemical evolution, and nuclear theory for the structure and reactions of very neutron-rich nuclei. This review paper was initiated at a three-week International Collaborations in Nuclear Theory program in June 2016 where we explored promising r-process experiments and discussed their likely impact, and their astrophysical, astronomical, and nuclear theory context.

“…Large arrays of detectors for γ-ray measurements coupled with auxiliary particle detection systems provide a powerful and versatile tool for studying exotic nuclei through nuclear spectroscopy at radioactive ion beam facilities. Decay spectroscopy experiments are performed at a number of radioactive beam facilities world-wide, such as with the EURICA setup at RIKEN [1], the beta counting station at NSCL [2], the X-Array and SATURN at ANL [3], the ISOLDE decay station [4], the implantation and decay station at Lanzhou [5], the identification station at SPIRAL [6] and in the past the RISING setup at GSI [7,8] which is transitioning to DESPEC at FAIR [9]. Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei, GRIF-FIN [10], is a new experimental facility for radioactive decay studies at the TRIUMF-ISAC laboratory [11] located in Vancouver, Canada.…”

Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei, GRIFFIN, is a new high-efficiency γ-ray spectrometer designed for use in decay spectroscopy experiments with low-energy radioactive ion beams provided by TRIUMF's Isotope Separator and Accelerator (ISAC-I) facility. GRIFFIN is composed of sixteen Compton-suppressed large-volume clover-type high-purity germanium (HPGe) γ-ray detectors combined with a suite of ancillary detection systems and coupled to a custom digital data acquisition system. The infrastructure and detectors of the spectrometer as well as the performance characteristics and the analysis techniques applied to the experimental data are described.

“…The experiment was performed in the continuous beam mode, which has a higher beam efficiency compared to the traditional beam-on/off mode [20,21]. By correlating the implanted nuclei with their subsequent β-particles within the same pixel or adjacent pixels of the DSSD, the β-decay properties of the implanted nuclei could be measured with much less disturbance from other unstable nuclei and the random background [22].…”
