An electron source with a plasma cathode based on a low-pressure arc discharge having a grid (layer) stabilization of the emission (cathode) plasma boundary and the open edge of the anode plasma has been used to study the deflection of a broad intense submillisecond electron beam from the electron source axis by a leading magnetic field. Measurements of the energy density distribution of the generated electron beam were made both under conditions of its deflection and in the mode of “direct” transport, when the collector target is in direct line of sight from the emission electrode. It was experimentally shown that the stability of the electron source operation with a beam deflection significantly increases. It allows to expand the range of beam parameters, which opens up new possibilities for use the electron source for both scientific and technological purposes.
