[Program for calculating diagnostic x-ray spectra].
A code written in BASIC is described which calculates x-ray spectra for tube voltages from 20 to 150 kVDC. Data for the spectral distribution, the mean photon energy, kerma in air, mean energy of the kerma distribution together with 1. and 2. half-value layers for aluminum are obtained. Numerical values for the differential energy intensity function and the Thomson-Whiddington constant were taken from Birch et al. (6). For target angles up to 30 degrees agreement between calculated and experimental data is good. For larger angles some discrepancies appear which could be either due to increased filtration by tungsten (surface roughness) or limited applicability of the data used. The program is tailored to be run on a personal computer.
