Features of the motion of charged particles in the field of the high-frequency impulse of large intensity

The results of analytical and numerical examinations of features dynamic of charged particles in field of intensive electromagnetic waves are reported. It is shown that the trajectories of particles, which has initially different phases concerning of the homogeneous wave, essentially discriminate. As a result, the accelerated bunch breaks down. Trajectories of articles in a field of an electromagnetic impulse differ from each other a little. This feature allows using impulses for effective acceleration of clots of charged particles
