A method for the calculation of bremsstrahlung spectra produced by 5–30 MeV electrons is described for the case of a thick tungsten radiator at observation angles from 0° to 20°. The computation is based on Shiff integrated-over-angle bremsstrahlung cross-section and includes energy losses, absorption and multiple scattering of the electrons in the radiator, the variation of the bremsstrahlung cross-section angular distribution with photon energy, and the absorption of radiation in the target material. The results obtained by the offered method were compared with known experimental data and Monte Carlo calculations of thick target bremsstrahlung spectra. A basic advantage of this method is that it needs only a small memory and short computing time. |
