RSIC COMPUTER CODE PSR-042
1. NAME AND TITLE
DUFOLD: Derivative Unfolding Code - Determination of Neutron Spectra from NE-213 Pulse
Kansas State University, Manhattan, Kansas.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360/370.
4. NATURE OF PROBLEM SOLVED
DUFOLD determines neutron energy spectra to obtain meaningful and reproducible radiation
5. METHOD OF SOLUTION
DUFOLD develops a suitable unfolding technique, based on a derivative method. The effects of
varying scintillator size are considered and it is applicable for various neutron angular distributions.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for DUFOLD.
8. COMPUTER HARDWARE REQUIREMENTS
DUFOLD is operable on the IBM 360/370 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
