  In this paper we present the results of a systematic numerical analysis of
the channeling properties of electrons and positrons in oriented straight and
periodically bent diamond(110) crystals. We analyse dependence of the intensity
of the radiation emitted on the projectile energy as well as on the bending
amplitude. The analysis presented is based on the grounds of accurate numerical
simulations of the 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.
