Аннотация
As known, the dipole approximation of channeling radiation (CR) successively overestimates the radiation yield, when the electron-beam energy approaches and exceeds 1 GeV. Consequently, we applied the nondipole approximation to simulate positron production via conversion of CR into e(+)e(-)-pairs in the scheme of a so-called hybrid positron source. GEANT4 simulations of positron spectra obtained from an amorphous tungsten converter at irradiation by <100> axial CR generated in tungsten and diamond single crystals are presented. For comparison, we calculated the CR spectra in dipole and nondipole approximation.
