1. NAME AND TITLE

ENEDEP: Energy Deposition Code System for GE 265 Time-Sharing System.

2. CONTRIBUTOR

Hughes Aircraft Company, El Segundo, California.

3. CODING LANGUAGE AND COMPUTER

Extended Basic (PDP-10); GE 265.

4. NATURE OF PROBLEM SOLVED

ENEDEP is designed to provide first order approximate treatment of gamma radiation effects in laminated materials based on idealized simple and good geometry. Multiple collision and scattering events are not included in the analysis.

5. METHOD OF SOLUTION

Calculation is based on numerical integration of the product of mass absorption coefficients and local fluence in all energy level ranges.

6. RESTRICTIONS OR LIMITATIONS

The simple geometry assumption must be kept in mind in assessing applicability of the calculation.

7. TYPICAL RUNNING TIME

About 80 seconds of calculation time is required on time share computing terminals for one set of fluence and equivalent blackbody temperature.

8. COMPUTER HARDWARE REQUIREMENTS

ENEDEP is operable on the GE 265 time sharing computer system.

9. COMPUTER SOFTWARE REQUIREMENTS

ENEDEP is written in Extended Basic language, compatible with the GE 265 Time Sharing System.
