Abstract
In an electron beam generator where the heating current for the cathode is transformed by an insulating transformer 7 disposed on the high-voltage insulator 4 of the beam head, the primary winding of this insulating transformer 7 being connected to ground potential, and where a single-pole high-voltage connection 2 and a single-pole high-voltage cable 2 connect the beam head 3 to a high-voltage generator 1, the high-voltage cable 2, at its terminal ends, has a protective resistor 10 corresponding to the surge impedance of the high-voltage cable 2 in order to reduce the damages to insulating and component parts.
