Monte Carlo calculation of characteristics of γ-beams produced by coherent bremsstrahlung at Fermilab

Abstract The energy spectra of the γ-beams which can be produced at Fermilab are calculated by modeling the production and absorption in single crystals, taking into account the energy and angular divergence of the electron beams. The results confirm that, replacing the amorphous targets by crystals, one can increase the γ-beam intensity in the high-energy region.
