Special Instructions:
This file describes the code associated with MAMSPEC.C, a "C" language 

subroutine which calculates realistic x-ray spectra for molybdenun, rhodium, 

and tungsten anode x-ray tubes between 18 and 42 kV.  The spectra that are 

produced do NOT include any added filtration - the only filtration of the 

spectra are by the (approximately) 0.5 mm Be window of the x-ray tube, and 

any self filtration by the anode itself.



To compile the subroutine, you'll need three data files (included in this 

EPAPS directory):



MOLY.H

RHODIUM.H

TUNGSTEN.H



Complete instructions for using MAMSPEC.c are given in the file itself as a 

header.  Also included in this EPAPS directory is a calling program, 

MAINPROG.c, which calls MAMSPEC.c and calculates a series of 

mammography x-ray spectrum and stores them in ASCII files with self 

evident names.

A run time program MAINPROG.EXE is also included which runs under 

DOS on a PC, and this code actually generates the spectral data files.  If your 

machine runs emulated DOS (e.g. NT 4.0), this program may not work.



These files are presented in a form most conducive to understanding, and are 

not optimized for speed or memory usage.  Good luck.
