Can the 88-Inch Cyclotron Save the Periodic Table?

Fast Machine Learning-Enabled Uncertainty Quantification for Radiological Mapping

Illustration of the radiological mapping and image reconstruction process, which plays a critical role in many nuclear security related applications. A detector system carried by an unmanned aerial vehicle scans the field to measure the counts due to environmental background and potential radioactive sources. The data collected during the mapping is processed on an edge computer. With traditional methods, such as MLEM, the major results output from the computer is a map showing the estimated radioactivity intensity. Using Bayesian methods, the major results output includes not only a radioactivity intensity estimate, but also their associated uncertainties. (Credit: Jayson R. Vavrek)

Energy-energy Correlators to Probe Particle Hadronization at Colliders

Energy-energy correlators (EECs) measure the correlations between two energy flows with an opening angle at colliders and can be described by the transverse momentum dependent di-hadron fragmentation functions (Credit: Feng Yuan)

Tracing a New Astrophysical Pathway for Making the Heavy Elements

Three labeled circles – connected by double-ended arrow lines, indicating a continuous, integrated, multidirectional process – surround a center rectangle with the words 'i process' on a background image of a starfield and multicolored nebula. The top circle says "Astrophysical Modeling" with an abstract graph image showing a cloud of rainbow-colored grid lines. The lower right circle says" Nuclear Data" and has an image of small bubbles or circles indicating an abstract configuration of subatomic nuclear particles. The lower-left circle is labeled "Astronomy" with a cartoon image of a telescope.

Behind the Science: FIONA

Data from Proton and Ion Targets Offers Synergies to Probe Meson Structure

Photoproduction of the ρ’ meson can occur on either proton or heavy (lead) nuclei. The two possibilities lead to the same 4-pion mass spectrum. (Credit: Neha Devi et al)
