    Abstract: Disclosed are cathode units for use in fluorescent discharge lamps which include a stem element adapted for sealing engagement with an end of an elongated vitreous/glass tube, first and second electrode support wires extending axially through the stem element, and a filament electrode which is oriented substantially axially with respect to the support wires. The support wires each have a inwardly-directed tip portion and the filament electrode is attached thereto. The ends of the filament electrode are attached to the support wires by welding. In alternative embodiments, the disclosed cathode unit can further include an electrode shield assembly.

    Abstract: An integral cathode (200) for use with x-ray devices (102). The integral cathode (200) includes an emitter (202) made of a refractory metal such as tungsten, preferably doped with rhenium to afford malleability during constructions and assembly. The integral ctahode (200) also includes a support cartridge (204), preferably composed of an electrically non-conductive material such as ceramic, in which the emitter (202) is received. The support cartridge (204) electrically isolates the cathode (200) from the other components and structures of the x-ray device (102). Additionally, the support cartridge (204) serves to impose, and maintain, a parbolic curve in the emitter (202). The parabolic form of the emitter (202) naturally shapes an electron beam by causing electrons discharged from the emitter to converge at a focal spot (106). In this way, both the emission and focusing functions of the cathode (200) are integrated and performed by a single part.
