Radiation and ionization energy loss of relativistic channelled electrons in crystal - a computer experiment

For estimating radiation and ionization energy losses of relativistic channelled electrons in a crystal are calculated the trajectories of electrons at the energy 1 GeV, moved in a germanium crystal near the 〈1000〉 direction, by means of the multistring model. The problem is solved numerically by the Runge-Kutta method. Results are presented of calculations of electron beam energy losses due to ionization and radiation in dependence on the penetration depth in a crystal for different initial angles of disorientation. Spectra of ionization losses for the zero angle of electron beam incidence on the crystal axis are shown for different target thicknesses.
