RSIC COMPUTER CODE PSR-044

1. NAME AND TITLE

BRMSTK: CSEWG Integral Data Testing Shielding Experiment Code System.

2. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 360/370 (A), CDC-6600 (B).

4. NATURE OF PROBLEM SOLVED

BRMSTK presents the experimental and calculational details for a CSEWG integral data testing shielding experiment. It tests a given set of neutron total cross sections or gamma-ray cross sections for iron, oxygen, nitrogen, sodium, or stainless steel.

5. METHOD OF SOLUTION

An NE-213 scintillation detector is used. Separation of neutron- and gamma-induced pulses is made by a modified Forte circuit. The unfolding of the pulse-height distributions is accomplished using the FERDOR code.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

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

8. COMPUTER HARDWARE REQUIREMENTS

BRMSTK is operable on the IBM 360/370 computer (A) or the CDC-6600 computer (B).

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.
