    Abstract: A method for regulating the beam current in industrial chargecarrier beam apparatus in which, by direct measurement of a beam of charge carriers produced in pulse form within the region of the beam path, measurement signals, which in each case are dependent essentially on the peak value of the pulse amplitudes, are derived for the subsequent formation of analog control variables serving for the regulation of the beam current, the measurement signals being first stored in each case in accordance with a pulse spacing.
