3. DESCRIPTION OF PROGRAM OR FUNCTION

This point-source, polychromatic, discrete energy X-ray transport and energy deposition code system calculates first-order spectral estimates of X-ray energy transmission through slab materials and the associated spectrum of energy absorbed by the material.
top ]
4. METHOD OF SOLUTION

X-ray source spectra may be internally generated and normalized (Kramer oR Plank spectrum), read from data  files, or read from an electronic library. Virtually any material consisting of the first 100 atomic elements may be specified as a shield or absorber using a common symbolic format. The calculated spectra may be selectively written to data files which in turn may be used as input to further calculations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Because this software is written in VAX Fortran, which is a superset of ANSI Fortran 77, and takes appropriate advantage of VMS system routines and run-time library functions, its transportability is limited.

6. TYPICAL RUNNING TIME

The programs take only a few seconds to execute interactively.
top ]
7. UNUSUAL FEATURES OF THE PROGRAM

One aspect of this software that is believed unique is its ability to parse chemical compounds and alloys that are entered in a conventional symbolic format and calculate the relative mass of the constituent elements.
