Dedicated detector for verification of X-ray energy in the linear accelerators for cargo screening and industrial radiography

The novel type of detector for X-ray energy evaluation has been developed. Thanks to a simultaneous analysis of the attenuation of X-rays by different thicknesses of well known material, the maximum energy of electrons on the conversion target can be deducted. Fast operation allows for pulse-to-pulse measurement, which is a must for modern, interlaced-energy cargo inspection systems. In this article the construction of the detector and software description are presented.
