The structure of the field in two intersecting linearly polarized beams (pulses) is considered. It is shown that in intensity distribution of the intersecting beams, in contrast to the single beam, account must be taken of the linear corrections for the parameter £ = 1 /kpa. The calculation of the trajectory, the residual kinetic energy and angles (polar and azimuthal) emission of a probe electron from the interference of Gaussian pulses was done.
Calculation of the parameters of the relativistic motion of the electron leads to a deterministic form. In the intersecting fields, unlike a single pulse, the azimuthal angle and the residual kinetic energy are not symmetrical in the initial polar angle. The acceleration in the new scheme is 5 times more than the direct acceleration in a single pulse, i.e. the capture of the second type in the "trap" is realized. The divergence of the electron beam decreases by about 2 times. The method of calculation of power energy-angular spectrum can be applied to this acceleration scheme [1].
The work was partially supported by the program 2018-06 of RAS "Extreme light fields and their interaction with matter".
