PROPX AN X-RAY MANIPULATION PROGRAM

An interactive microcomputer program that performs some manipulations on an input x-ray spectrum is introduced and described. The program is used to calculate the effect of absorption by filters, transmission through filters, responsivity of photocathodes, responsivity of absorptive detectors, folding of responses, plotting of cross sections, and calculation, as a function of electron temperature, of the response due to a bremsstrahlung spectrum. Fluorescence from the targets is not included. Two different x-ray libraries are offered, one covers the x-ray range 30-10 000 eV with 288 energy points, and the other covers the energy range 10 eV-1 MeV with 250 energy points per decade.
