Abstract
When an electron accelerator operates in the bremsstrahlung generation regime, the initial beam is transformed in the extraction facilities of the accelerator into a flux of secondary particles - electrons and bremsstrahlung photons (e,X radiation). The ratio of the radiation components in a given plane depends on the initial energy of the electrons and the thickness and materials used for the extraction components. This article describes a simplified method for evaluating the main characteristics of e,X radiation in the radiation formation channel. The method is based on measuring the thickness of the components of the channel in units of electron path lengths in the continual stopping approximation. This makes it possible to express the radiation characteristics of materials with a wide range of atomic numbers (7-73) and electron energies (5-100 MeV) in a unified form. The possibilities of the method are demonstrated by the results of a simulation using the PENELOPE/2006 system of computer programs.
