Abstract

In this paper we present the results of a systematic numerical analysis of the channeling properties for electrons and positrons in oriented straight and periodically bent diamond(110) crystals. We analyse the dependence of intensity of radiation emitted on the projectile energy as well as on the bending amplitude. The analysis presented is based on grounds of accurate numerical simulations of a channeling process. The simulation parameters, such as the crystal orientation, thickness and bending parameters of the crystals as well as the energy of the projectiles, were chosen to match those used in past and ongoing experiments. The peculiarities which appear in the radiation spectra are attributed to the interplay of various radiation mechanisms. The analysis performed can be used to predict and explain future experimental results.
