Abstract
A high-voltage power supply for an electron-beam gun with a heatable cathode and an anode and of the type having an electronic switch connected in the current circuit for the cathode and controllable for blocking the current to the cathode, includes an impulse protecting filter connected in the current circuit for the cathode. The filter comprises a capacitor connected in parallel to the cathode, a choke connected in series with the cathode current circuit, a blocking diode and a discharge resistor connected in series therewith, with the diode and resistor connected in parallel with the choke.
