RSIC COMPUTER CODE PSR-060

1. NAME AND TITLE

RESPMG: Response Matrix Generation Code System.

AUXILIARY PROGRAM

O5S: Response Function Generator: An O5R Monte Carlo Code for Calculating Pulse Height Distributions Due to Monoenergetic Neutrons Incident on Organic Scintillators.

2. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

Fortran IV and Assembler Language; IBM 7090.

4. NATURE OF PROBLEM SOLVED

RESPMG generates an accurate and detailed family of monoenergetic response functions or a numerical matrix which accurately describes the pulse-height response of a unique organic scintillator (unique in terms of atomic composition, volume, shape, and physical dimensions) to monoenergetic neutrons, or other particles of interest, closely spaced in energy over the entire energy range of interest.

5. METHOD OF SOLUTION

RESPMG consists of some 25 subprograms and functions which may be roughly separated into three categories. The first group performs basically service functions--printing, punching, plotting, data input/output, etc.

RESPMG accepts, as input from the PSR-14/O5S results, a normally rather limited set of computed responses. To expand this limited set to the number and detail required for the final matrix, a group of programs known as the "TERP" package is used to perform a variety of services concerned with interpolation.

The final group of programs consists of those directly concerned with the operations and computations involved with the calculation of the final matrix.

6. RESTRICTIONS AND LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running times for RESPMG.

8. COMPUTER HARDWARE REQUIREMENTS

RESPMG is operable on the IBM 360/370 or IBM 7090 computers.

9. COMPUTER SOFTWARE REQUIREMENTS

Fortran IV and Assembler Language compilers are required.
