RSICC CODE PACKAGE CCC-837

1.         NAME AND TITLE

     CEPXS: Coupled Electron-Photon Cross Section

2.         CONTRIBUTOR

Sandia National Laboratories, Albuquerque, New Mexico.

3.         CODING LANGUAGE AND COMPUTER

Fortran 90 source code and Perl scripting (C837MNYCP00).

4.         NATURE OF PROBLEM SOLVED

CEPXS generates multigroup-Legendre cross sections for coupled photon-electron-positron transport calculations. The cross sections are primarily intended for use in the SCEPTRE (C00826) and ONELD deterministic transport codes and the MITS (C00792) (multigroup-ITS) Monte Carlo code.

5.         METHOD OF SOLUTION

Numerical processing of photon, electron and positron physics data into multigroup-Legendre form used by standard radiation transport codes.

 

6.         RESTRICTIONS OR LIMITATIONS

Energy range limited to 1 keV – 100 MeV

7.         TYPICAL RUNNING TIME

Input file dependent, generally a few seconds to a few minutes.

8.         COMPUTER HARDWARE REQUIREMENTS

Minimal

9.         COMPUTER SOFTWARE REQUIREMENTS

Perl interpreter and Fortran 90 compliant compiler.
