    Abstract: An apparatus for assembling and inspecting an electron gun of a cathode ray tube includes a mandrel 5 and a measuring nozzle 2. The mandrel 5 has an outer diameter larger than the electron-beam-transmission hole of the Gm electrode 30. The mandrel 5 abuts against the Gm electrode 30 from G3 electrode 40 side, to seal the electron-beam-transmission hole of the Gm electrode 30. The measuring nozzle 2 has a tip that can be inserted through the electron-beam-transmission holes of the G1 and G2 electrodes from the G1 electrode side, and blows air toward the mandrel 5. A clearance between the G2 and Gm electrodes are measured according to the change in pressure of the blown air. It is possible to measure the clearance between the electrodes required for assembling the electron gun having the Gm electrode with a small electron-beam-transmission hole.

    Abstract: Electron-optical device having two elongate emitting regions arranged symmetrically with respect to a longitudinal axis for producing two electron beams having an elongate cross-section. By means of electron grids, the two beams are focused at the same point of an electron target arranged transversely to the longitudinal axis and having a short central axis and a long central axis. The elongate emitting regions have their smallest cross-section parallel to the scanning direction of a device, cooperating with the electron-optical device, for scanning a target arranged transversely to the longitudinal axis.

    Abstract: Travelling wave tubes designed to operate interchangeably at low power cw and high pulsed power have grids to gate the pulses and to switch the peak beam current between two values. To preserve optimum beam-focus conditions, the beam diameter should be simultaneously switched. A grid covering the central region of a concave cathode draws the low-current, small beam for cw operation or the central part of a large pulsed beam. A second grid controls added pulsed emission from the surrounding annular region of te cathode. To provide the proper ratio of beam sizes and uniform cathode loading, the cathode has radially varying radius of curvature. A hyperboloid of revolution is a good shape.

    Abstract: The control grid structure for a convergent flow electron gun includes a corrective electrostatic lens associated with each of the beam passageways through the grid. The corrective electrostatic lenses increase in focusing strength taken from the outside of the beam toward the center of the beam to compensate for beamlet defocusing forces occasioned by the relatively large central aperture in the anode of the gun. In a preferred embodiment, the corrective electrostatic focusing lens structure comprises a second control grid portion interposed between a first control grid portion and the anode. The second control grid portion is thermally shielded from the cathode via the first grid portion for inhibiting unwanted thermionic emission from the composite control grid structure.

    Abstract: Triode electron gun with positive control grid, with emitting cathode, and with acceleration anode, providing a concentration and emission of electrons directed along straight and parallel paths. Thus gun includes several elementary guns distributed around a single axis, the axes of the guns converging toward one and the same point on the axis situated at the entrance to an axial conical conduit drilled in the anode. The electrons produced in each elementary gun by an emitting pellet go through a concentrator and then through a conduit in alignment with the axis of each gun and perforated in a single thick grid. The invention can be applied in metallurgy for melting and heating.
