Abstract: The invention pertains to a process for the control of the strike positions of a plurality of electron beams on a melting bath. In this case, the light beams issuing from the surface of the melting bath are sent to a radiation splitter, the separated beams of which, as the case may be, are sent via additional radiation splitters to photoelectric sensors. The output signals of these sensors are sent to a control, which guides the electron beam guns, from which the electron beams issue.
