Science drives technology, and technology enables science. Such is the case in accelerator-based nuclear physics, where the scientific need to measure certain reactions has been the driving force behind the development of new beams, and in particular, radioactive ion beams. In turn, the availability of radioactive ion beams has enabled new areas of research to be explored. Despite great advances, progress remains challenging. In most cases, significant development is required for each new beam at each individual facility. Particularly challenging are cases in which chemistry inhibits the production and extraction of the ions from the source, when the intensities required are high, and when gaseous targets are required to probe the nuclear reactions. Some direct measurements of cross-sections for nuclear astrophysics provide the “perfect storm” to inhibit experimental progress.
