RSIC CODE PACKAGE CCC-301


1. NAME AND TITLE

ELPHO: Three-Dimensional Monte Carlo Electromagnetic Transport Code System.

AUXILIARY ROUTINES

CYLGEOM: Cylindrical Geometry Routine.

GENGEOM: General Geometry Routine.

BREM: Bremsstrahlung Cross-Section Data Generator.

FLRAN: Data Generator.

ELPHO was designed as one of the calor codes developed to design and analyze calorimeter systems which are packaged in CCC-178/HETC.

2. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

FORTRAN IV and Assembler language; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

ELPHO was designed for basic electromagnetic transport studies. ELPHO reads ``collision'' tapes which have been generated by HETC and obtains the produced pions, gamma rays, electrons, and positrons from muon decay which are the sources for the electromagnetic cascade.

5. METHOD OF SOLUTION

ELPHO uses the Monte Carlo method.

6. RESTRICTIONS OR LIMITATIONS

ELPHO is set to handle 2000 incident particles. This number can be changed by altering common specifications as described in the document.

7. TYPICAL RUNNING TIME

The packaged sample problem required about 15 minutes on the IBM 360/91.

8. COMPUTER HARDWARE REQUIREMENTS

An IBM 360/370 computer is required.

9. COMPUTER SOFTWARE REQUIREMENTS

FORTRAN IV and Assembler compilers are required.

11. CONTENTS OF CODE PACKAGE

Included are the referenced document and one (1.2MB) DOS diskette which contains the source code and sample problem input and output.
