Free online tool for calculating radioisotope production yields in stacked target assemblies. Simulate proton, deuteron, alpha, and helion irradiations using evaluated nuclear data (TENDL-2024, ENDF/B-VIII.1, JENDL-5, JEFF-4.0). Compute activation yields, saturation activities, depth profiles, and cooling curves with Bateman decay chain resolution.
Features: cross-section lookup, PSTAR/ASTAR tabulated stopping powers (more accurate than Bethe-Bloch), isotopic enrichment, multi-layer stacks, monitor foils, and exportable results. All computation runs locally in your browser — no server, no data upload.
