In this article, the formation of given distributions of electron fluxes on the surfaces of irradiated objects using magnetic fields of one-dimensional and two-dimensional scanners was studied. The types of time-dependences of the change in the magnetic field was determined, providing both uniform and given distributions of the electron density on the irradiated surface. The influence of the energy and angular spread in the electron beam on the change in the density of particles on the surface was analyzed. The influence of these factors can be compensated by changing the magnetic field. For (X,Y)-scanner that generates electron beams: the main one (incident perpendicular to the object) and additional (incident angles of 60…75° from the perpendicular to the object), a significant effect of the energy spread on the incident angles of the additional beam was shown.
