THE PECULIARITIES OF THE REGULAR AND QUASI-REGULAR MOTION OF CHANNELED ELECTRONS

The finite motion of axial channeling electrons with energy from few MeV up to tens of MeV have been simulated in a computer. For the quasiregular type of motion, electron trajectories with closely lying initial parameters diverge in the phase space. The stochasticity of the transverse energy distribution caused by this divergence, when the string potential is disturbed, leads to difficulties in the dynamical prediction of the system behaviour. For predicting the frequencies in the peak region of radiation spectrum it is sufficient to consider only electrons with quasiresonance trajectories. The radiation calculations are compared with experimental results.
