Abstract: The present invention relates to a grid electron tube whose cathode is comprised of an emissive part (12) which delimits a substantially central recess (11). Said cathode reduces considerably the emission of spurious electrons of the grid by contributing to its cooling. Application particularly to electronic tubes known as IOT.

Abstract: An electron gun which is rugged, provides good thermal decoupling of the cathode, permits precise alignment of the electrodes to be achieved easily and allows geometric changes to be carried out with ease is described. In the cathode assembly three set screws (18) and a split ring (20) of insulating material are used to secure the cathode. Alignment is achieved by suitably adjusting the set screws and because contact can be limited to the three set screws thermal coupling is reduced. Similarly a Whenelt electrode (32) is secured and aligned by a further group of set screws (35). Finally, the anode (42) is secured to replaceable stand-offs (2) by means of screws (48) passing through oversized holes in an anode plate. The oversized holes permit easy alignment and the use of stand-offs permits the spacing between anode and cathode to be changed as desired by replacing the stand-offs.

Abstract: An electron beam sterilizing device comprises; an electron-generating filament (110), a grid (114a-b) connected to a voltage source, a beam shaper (128), and an output window (118). A high voltage source generates a high voltage potential between the electron-generating filament and the output window, for acceleration of electrons. The usability of the device is enhanced in that the electron-generating filament and/or the grid electrode comprises at least two operational portions for variation of the current and form of an output electron beam.
