Functional Expansion Tallies Using MCNP6 PTRAC Files [Slides]
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Accuracy is vital for many radiation transport applications. Monte Carlo (MC) codes are the most accurate, but they are expensive for fine meshes. Functional Expansion Tallies (FETs) yield smoother, lower-variance results with far fewer degrees of freedom.
