1. NAME AND TITLE
ELPHO: Three-Dimensional Monte Carlo Electromagnetic Transport Code System.
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.
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.
