Since the discovery of the atomic nucleus, our appreciation of the role of nuclear physics in the universe has expanded dramatically. An understanding of the chemical evolution of the universe, and the energy generation and production rates of individual radionuclides, requires a detailed understanding of reaction rates involving very low cross sections, or reactions involving unstable nuclei. Many of these unstable nuclei will be available with unprecedented intensities at the Facility for Rare Isotope Beams (FRIB), currently under construction, which will enable many of these reactions to be well-constrained for the first time. In addition to direct measurements at astrophysical energies, transfer reactions, such as (d,p) (d,n) and (3He,d) reactions, can provide constraints on the single-particle properties of bound and resonant states, and can be used are used for surrogate measurements of neutron capture. Advances in instrumentation, techniques and targetry to fully exploit the advances in radioactive beam production. To this end, new instrumentation such as GODDESS (a coupling of the Oak Ridge Rutgers University Barrel Array to GRETINA/GRETA gamma-ray tracking array), the Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas jet target, and advances neutron detection techniques have been developed. An overview of these devices and their physics in the FRIB era will be presented.
