Paper Abstract

SPECTRA is a personal computer-based application software system which effectively supports our research work on the flash x-rays. It consists of four program modules: (1) data- entry function, (2) energy spectra calculation function, (3) spectra curves displaying function, and (4) image simulation function. Data of tube voltage and tube current from the flash x-ray source can be entered either through the data-storage units automatically or by manual input operation. Calculation of energy spectra is based on Kramers' equation. Source date and the results of calculations can be saved in the external storage. Saved data can be used as input data of the above functions (3) and (4). In function (4), under the specified conditions of voltage, current, and the x-ray absorbers, the intensity of the x rays which permeate a given physical body model is calculated for its every subdivided part and its simulated radiographic image is displayed on the CRT screen.
