Determination of instantaneous effective energy of the X-ray tubes bremsstrahlung

摘要

The method of instantaneous effective energy of the bremsstrahlung X-ray tubes determination by system of two semiconductor detectors is described. Detectors are based on epitaxial GaAs structures and circuit electronics of measurement allowing to determine the X-ray beam effective energy with error 5% in 20 - 80 keV energy range in nonlinearity condition of detector photosensitivity steepness.
