A Compton scattering spectrometer for determining X-ray photon energy spectra

摘要: With the use of more sophisticated diagnostic technologies it is becoming increasingly important to know energy spectra primary photons from clinical X-ray tubes. At high fluence rates used under working conditions, necessary greatly reduce number detector per unit time in order avoid pulse pile-up. The Compton scattering method very suitable for this reduction and hence has been further developed work primary-photon range 20-200 keV. movement electrons target causes an broadening scattered photons. This results a decreased resolution, which particularly seen as smearing out characteristic peaks anode material. Comparison between spectrum obtained using spectrometer unfolded with authors' reconstruction measured directly beam shows good agreement even though relatively simple algorithms have used.
