Annotation:  The results of reconstruction of the electron beam flux density distribution in the transverse plane are presented in the paper. The reconstruction is based on the multi-angle wire scanning and the mathematical processing via the inverse Radon transformation. The data set is performed by thin metal plate multiple scanning in a plane perpendicular to the beam axis at different angles with a specified offset. The intensity of the beam current was measured by a Faraday cup during the experiment. Within framework, the dependence of the beam current from the position and orientation angle of the plate was transformed into a dependence from the vertical and horizontal coordinates in the cross section
