A method for analysis and optimization of electron accelerator exit devices under bremsstrahlung generation mode

The method of the analysis of a mixed å,X-radiation field along a path of the output target devices of the electron accelerator is proposed. The concept of stopping length of a path and representation of a real path as multicomponent layered target with infinite cross-section size lays at the heart of a method. A set of basic characteristics of the å,X-radiation is formulated. It is shown, that the description of target devices in terms of stopping length allows to reduce the basic characteristics of radiation to unified form in the range of initial electron energy 5 - 60 ÌeV at a value of the nuclear number of target material 6 - 73. As a result, three stages of the å,X-radiation formation differing by a ratio of its component intensity are established. Procedure of optimisation of a path in order to receive the specified values of basic characteristics is described.
