Abstract: A method is provided for forming a three-dimensional article through successively depositing individual layers of powder material that are fused together so as to form the article. The method includes: providing at least one electron beam source emitting an electron beam; providing a leakage current detector for sensing a current through the anode and/or the Wehnelt cup; providing a low impedance voltage source connectable to the Wehnelt cup via a switch, where the voltage source is having a more negative potential than a negative potential applied to the cathode; and protecting the cathode against vacuum arc discharge energy currents when forming the three-dimensional article by providing the Wehnelt cup to the low impedance negative voltage by closing the switch when the leakage current detector is sensing a current through the anode and/or the Wehnelt cup which is higher than a predetermined value.

Abstract: The present disclosure provides for various advantageous methods and apparatus of controlling electron emission. One of the broader forms of the present disclosure involves an electron emission element, comprising an electron emitter including an electron emission region disposed between a gate electrode and a cathode electrode. An anode is disposed above the electron emission region, and a voltage set is disposed above the anode. A first voltage applied between the gate electrode and the cathode electrode controls a quantity of electrons generated from the electron emission region. A second voltage applied to the anode extracts generated electrons. A third voltage applied to the voltage set controls a direction of electrons extracted through the anode.
