Abstract

1,217,037. Electron beam apparatus. UNITED AIRCRAFT CORP. 29 March, 1968 [16 June, 1967], No. 15329/68. Heading H1D. A cold cathode glow discharge electron gun has a non-dissipative mask 17 and a cathode 10, wherein an electron beam is produced through an aperture 18 in the mask and the mask is moved relative to the emitting surface of the mask so as to produce relative motion of the electron beam. The gun structure may be annular as shown and the electron beam focused to weld a workpiece 15, alternatively the structure may be linear (Fig. 2, not shown). The mask may be provided with a plurality of apertures circumferentially distributed for producing a plurality of electron beams.
