An experimental study of current-density distributions of a technological electron beam

An experimental technique for the acquisition of current-density distributions of continuously operating electron beams with an electron energy of 60 keV is proposed. The measurement results for different cross-sectional areas of the beam with a power of 2.1 kW and a current density around 1 $\times$ 10$^{5}$ A/m$^{2}$ are given.
