    Abstract: An electron-beam controller (EBC) capable of controlling the power in an electron-beam is disclosed. The EBC can be implemented with an emitter, an extractor, a current mirror, and an input current having a magnitude responsive to the desired electron beam current. An EBC suited for low-efficiency emitters is also disclosed. A method for controlling the power intensity of an electron-beam over time is also disclosed. The method includes the steps of: (1) providing an emitter at a first voltage, (2) providing a target at a second voltage, (3) introducing an extractor at a controllable third voltage, (4) estimating the actual electron beam energy by sensing the emitter current; and (5) adjusting the third voltage in response to the sensed emitter current.

    Abstract: Cathode ray tube comprising an electron gun which is constructed in such a way that the gas pressure near the electron-emissive layer (30) of the cathode is lower than in the other parts of the tube. This can be achieved by reducing the aperture between the G1 (33) and G2 (36), by providing the G2 (36) with a skirt (43). The wall of the skirt, the G1 and the G2 may also be at least partly coated with a getter (41).

    Abstract: In an electron tube based on a cold cathode, a cesium source (17) containing Csx—Auy or Csx—Sby is provided near the cold cathode (7), preferably in contact with the first grid (9). Cesium is introduced into the source during activation of the tube. The vapor pressure of the cesium compounds is such that proper delivery of cesium is guaranteed throughout the life-time of the cathode.

    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: An electron has an electron-emitting region, a longitudinal axis and an arrangement of apertured electron grids along the axis. A first grid has an aperture for passing electrons, which aperture is located further outwards with respect to the longitudinal axis than the emitting region. One of the other grids is provided with a shield so as to shield the edge wall of the aperture, if it is located within direct view of the electron-emitting region, from incidence of positive ions.
