Inertial electrostatic confinement devices are one of the early designed fusion neutron generators that are usually used for the laboratory plasma ion confinement studies. If the deuterium gas is used, relatively high energy ions could generate fast neutrons during the well-known D-D nuclear fusion reaction process. Since the cathode electrode is exposed to high energy ions, this electrode suffers from high temperatures up to the melting point. Therefore, steady state operation is not possible for an extended time particularly at high power operations. This paper reports on the design and construction of a new cathode, including its high voltage feedthrough for the IR-IECF device at the plasma and fusion research school. Deionized water is used for cooling of the electrode to prevent high voltage breakdown. Both the theory and experimental results represent excellent heat removal even at more than three kilo-watts of ion power in continuous mode of operation.
