The motion and radiation of an electron in an accelerating scheme of two Gaussian beams intersecting at a small angle with antiparallel basic components of an electric field [1] are considered. The analysis of radiation is based both on the determination of the instantaneous radiation intensity along the trajectory of motion and on the determination of the maximum radiation characteristics (direction and duration of electromagnetic radiation) in the far zone.
The trajectories of motion and the structure of electron radiation in the field of a single Gaussian beam and in intersecting beams are compared. It is shown that the regularity of trajectories in one beam (two-dimensionality, axial symmetry, separation into quasi-straight sections) does not extend to motion in two beams. This qualitative difference in the trajectories leads to a lower intensity, longer duration of the radiation pulses at a higher residual kinetic energy of the electron in the intersecting beams.If the conditions of falling into the traps of the field are not met, the trajectory of the electron is close to the spiral, and the radiation to the synchrotron.
The work was partially supported by the program of RAS "Extreme light fields and their interaction with matter".
