Description

Great advances are happening in our understanding of our Galaxy and its physical phenomena, courtesy of missions such as TIGERISS (Trans-Iron Galactic Element Recorder on the International Space Station), which will be the first single instrument to look at elemental abundances spanning B to Pb. Planetary nuclear spectroscopy has also advanced and missions are visiting planets and asteroids never explored before, to determine their surface compositions. However, the accurate interpretation of these advanced observational data is contingent upon accurate cross-section data, which are currently quite lacking and inadequate. There are gaps in data and unreliable measurements abound, and there have been very little drive to address these concerns, especially for proton spallation (p,X) cross-sections in high-Z and high-energy regions, which are imperative to study cosmic ray origins and planetary compositions. To that end, our team has established a collaboration with various institutions to perform a series of cross-section experiments for the reaction channels of utmost importance. Our next experiment, measuring 52Cr(p,X) reactions at FRIB, MSU (the focus of this talk) is astrophysically important for constraining re-acceleration models and has no data exists on the reaction channel. This will be the first time a primary 52Cr beam will be generated.
