1. NAME AND TITLE
WINDOWS II: A Program for the Analysis of Spectral Data Foil-Activation Measurements.
PSR-136/WINDOWS is a simplified and slightly faster version of CCC-233/CRYSTAL BALL. Its name refers to its ability to model integral responses to a neutron flux. These responses may be thought of as views of the neutron spectrum through a "window" open between the bounds of integration and colored by the underlying response function.
WINDOWS II differs from PSR-136/WINDOWS in its types of output. All the subroutines that
permit direct plotting via CALCOMP commands were changed or deleted. Instead of plotting spectra
and "window" functions, this version creates several data sets. No new switches or parameters have
been introduced. The only change to note is that, in the procedural data, requests for plots are treated
as requests for output.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 370.
4. NATURE OF PROBLEM SOLVED
WINDOWS II is capable of unfolding neutron differential spectra estimating windows and detector
contributions, laying upper and lower bounds for integral response, and obtaining group fluxes from
neutron transport calculations.
5. METHOD OF SOLUTION
Instead of plotting spectra and "window" functions which existed in WINDOWS, WINDOWS II creates several data sets. This change allows users to use the interactive graphics capability which is available on the DEC-10 system.
WINDOWS II is more easily transported than WINDOWS because it includes no direct plotting
via CALCOMP commands.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for WINDOWS II.
8. COMPUTER HARDWARE REQUIREMENTS
WINDOWS II is operable on the IBM 370 computer.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
