    Abstract: The invention relates to a device for producing an electron beam, comprising a housing (12), which delimits a space (13) that can be evacuated and has an electron beam outlet opening; an inlet (16) for feeding a process gas into the space (13) that can be evacuated; a planar cathode (14) and an anode (15), which are arranged in the space (13) that can be evacuated and between which a glow-discharge plasma can be produced by means of an applied electrical voltage, wherein ions can be accelerated from the glow-discharge plasma onto the surface of the cathode (14). The cathode has a first part (14a) made of a first material, which forms a centrally arranged first surface region of the cathode (14), and a second part (14b) made of a second material, which forms a second surface region of the cathode (14) that encloses the first surface region. The first material can be heated by the impingement with accelerated ions to a temperature at which electrons escape the first material predominantly due to thermionic emission.

    Abstract: An ion-ion plasma source, that features a processing chamber containing a large concentration of halogen or halogen-based gases. A second chamber is coupled to the processing chamber and features an electron source which produces a high energy electron beam. The high energy electron beam is injected into the processing chamber where it is shaped and confined by a means for shaping and confining the high energy electron beam. The high energy electron beam produced in the second chamber when injected into the processing chamber ionizes the halogen gas creating a dense, ion-ion plasma in the processing chamber that is continuous in time.

    Abstract: A surface discharge device performing functions of a trigger and electron beam generator includes a cylinder shaped member formed from a dielectric material with dielectric constant ε>100, in which a central opening is formed having a conical or cylindrical shape. An internal electrode is electrically coupled to the internal surface of the cylinder shaped member. An external electrode covers the external surface of the cylinder shaped member. A triggering pulse is applied between the external and internal electrodes to generate emission of electrons in the central opening and formation of the conducting plasma to ignite the device and serve as a source of electrons for generating an electron beam. The conducting plasma charges a capacitor formed by the cylinder shaped dielectric member and the external electrode. The cylinder shaped member is positioned in a hollow cathode having a central bore hole in the bottom. An anode is positioned remotely from the cathode and an electric field exists dynamically in space between the cathode and anode for at least a portion of the duration of the triggering pulse.
