Interface to ENDL: Enhancing Nuclear Data Utilization with Geant4

The ENDL (Evaluated Nuclear Data Library) interface provides critical nuclear and atomic reaction databases developed at Lawrence Livermore National Laboratory. This collection includes binary collision cross sections, particle multiplicity distributions, energy/angular distributions of reaction products, and calculational constants in a point-wise format, specific to incident projectile energies. Collaborating with SLAC, we aim to integrate ENDL data into Geant4, paving the way for advancements in the simulation of nuclear interactions. ENDL is publicly available and encourages community engagement for future enhancements.

Presentation Transcript

  1. The ENDL interface KOI, Tatsumi SLAC 14th Geant4 Workshop Catana Italy

  2. Interface to ENDL • The evaluated nuclear and atomic reaction databases developed at Lawrence Livermore National Laboratory. • A collection of flat file databases which represent • Binary collision cross sections • Particle number multiplicity distributions of reaction products • Energy and angular distributions of reaction products • Derived calculational constants • In a point-wise format as a function of incident projectile energy on stationary targets. • The LLNL Computational Nuclear Physics (CNP) Group translated ENDF/B-VI, ENDF/B-VII, JEFF-3.1, JENDL-3.3 and other neutron incident evaluated reaction data libraries to ENDL. • http://nuclear.llnl.gov/CNP/translation/index.html • ENDL is open to public • SLAC and LLNL collaboration is developing G4ENDL which is interfacing ENDL from Geant4 • Hope to be a successor of Neutron HP.

  3. List of Isotope datatemporal (ENDL99) 14th Geant4 Workshop Catana Italy

  4. ENDL does not do Doppler broadening on flight • Prepare data for 3 temperatures • 3.00E+02, 1.16E+03 and 3.59E+03 [K] • Require XML parsing of “expat” • Validations on going • If you have specific channel want to investigate then let me know. • Mass problem • How to migrate into Geant4 • Like GDML? 14th Geant4 Workshop Catana Italy
