Estimating the Accuracy of Reconstructing Bichromatic Spectra of Electron Beams from Depth Dose Distributions

An algorithm is proposed for reconstructing the energy spectra of electron beams in the energy range of 5 to 10 MeV from depth dose distributions in an aluminum phantom, calculated via modeling using the GEANT4 program code. An estimate of the accuracy of the reconstruction of spectra consisting of two monochromatic beams is established that depends on the chosen energy step.
