Nuclear astrophysics with gas targets — •Konrad Schmidt — Institute of Nuclear and Particle Physics, TU Dresden, Germany

Nuclear astrophysics experiments will benefit from the development of next generation gas-target setups. The advantages of a localized, dense and pure target are discussed in detail by taking the example of the Jet Experiments in Nuclear Structure and Astrophysics (JENSA) windowless gas-jet target. JENSA enables the direct measurement of previously inaccessible reactions with radioactive ion beams provided by the rare isotope re-accelerator ReA3 at the National Superconducting Cyclotron Laboratory (NSCL) on the campus of Michigan State University (MSU), USA. The gas jet will be the main target for the Recoil Separator for Capture Reactions (SECAR) at the Facility for Rare Isotope Beams (FRIB). JENSA provides an unprecedentedly high number density of ∼ 10¹⁹ atoms/cm² and enables the direct measurement of various hydrogen and helium-induced astrophysical reactions.
