Weighted Delta-Tracking in Scattering Media
J. S. Rehak, L. M. Kerby, M. D. DeHart +1
In this work, we expand the weighted delta-tracking routine to include a treatment for scattering. The weighted delta-tracking routine adds survival biasing to normal delta-trackin…
Production of Energetic Light Fragments in CEM, LAQGSM, and MCNP6
Stepan G. Mashnik, Leslie M. Kerby, Konstantin K. Gudima +3
We extend the cascade-exciton model (CEM), and the Los Alamos version of the quark-gluon string model (LAQGSM), event generators of the Monte-Carlo N-particle transport code versio…
Energetic Light Fragment Production Capability in MCNP6
Leslie M. Kerby, Stepan G. Mashnik, Konstantin K. Gudima +3
The goal of this research is to enable MCNP6 to produce high-energy light fragments. These energetic light fragments may be emitted by our models through three processes: Fermi bre…
MCNP6 simulation of light and medium nuclei fragmentation at intermediate energies
Stepan G. Mashnik, Leslie M. Kerby
Fragmentation reactions induced on light and medium nuclei by protons and light nuclei of energies around 1 GeV/nucleon and below are studied with the Los Alamos transport code MCN…
Total Reaction Cross Sections in CEM and MCNP6 at Intermediate Energies
Leslie M. Kerby, Stepan G. Mashnik
Accurate total reaction cross section models are important to achieving reliable predictions from spallation and transport codes. The latest version of the Cascade Exciton Model (C…
Production of Heavy Clusters with an Expanded Coalescence Model in CEM
Leslie M. Kerby, Stepan G. Mashnik
The production of heavy clusters in nuclear reactions is important in a wide variety of applications: radiation shielding, space engineering and design, medical physics, accelerato…
MCNP6 fragmentation of light nuclei at intermediate energies
Stepan G. Mashnik, Leslie M. Kerby
Fragmentation reactions induced on light target nuclei by protons and light nuclei of energies around 1 GeV/nucleon and below are studied with the latest Los Alamos Monte Carlo tra…
Comparison of Expanded Preequilibrium CEM Model with CEM03.03 and Experimental Data, FY2013
Leslie M. Kerby, Stepan G. Mashnik, Arnold J. Sierk
Emission of light fragments (LF) from nuclear reactions is an open question. Different reaction mechanisms contribute to their production; the relative roles of each, and how they…
Production of Energetic Light Fragments in Spallation Reactions
Stepan G. Mashnik, Leslie M. Kerby, Konstantin K. Gudima +1
Different reaction mechanisms contribute to the production of light fragments (LF) from nuclear reactions. Available models cannot accurately predict emission of LF from arbitrary…
Preequilibrium Emission of Light Fragments in Spallation Reactions
Leslie M. Kerby, Stepan G. Mashnik, Arnold J. Sierk
The ability to describe production of light fragments (LF) is important for many applications, such as cosmic-ray-induced single event upsets (SEUs), radiation protection, and canc…
