HYRR HYRR

Radioisotope production in stacked targets

HYRR — Hierarchical Yield and Radionuclide Rates — predicts radio-isotope production in stacked target assemblies: ∫σ/dEdx integration with TENDL cross-sections, PSTAR/ASTAR tabulated stopping powers, and Bateman decay chains. Runs entirely in your browser.

What it does

Cross-sections

Charged-particle (p, d, t, ³He, α) reaction cross-sections from TENDL and other evaluated libraries.

Stopping powers

PSTAR/ASTAR tabulated stopping with Bragg additivity — more accurate than Bethe-Bloch at cyclotron energies.

Decay chains

Full Bateman solutions for production, irradiation, and cooling — depth-resolved through the target stack.

Stacked targets

Build multi-layer assemblies with custom materials; share configurations by link.
