    摘要: A directly-heated cathode for power electron tubes such as triodes, tetrodes or pentodes comprises a cylindrical sleeve constituted by a lattice of crossed wires forming the emissive portion of the cathode and by two conductive plates attached respectively to each end of the sleeve. In order to permit free deformation of the cathode, a flexible metallic bellows element is fixed between one of the plates and the corresponding end of the cylindrical sleeve.

    摘要: An electron tube includes cylindrical electrodes which are mounted coaxially. The electrodes include a cathode surrounded by a grid, with the cathode and the grid defining an input resonant cavity having an active zone. The cavity extends on both sides of the active zone. The central part of the active zone is located at a point where the voltage reaches a maximum. The resonant input cavity is folded back on itself so that both ends of the cavity are at the base of the tube.

    摘要: A grid for an electron tube with an axial beam which includes an apertured part through which the electrons of the beam are intended to pass. The grid is in the form of a bell and is made of a single material. The apertured part is located at the top of the bell but is placed in the bottom of a hollow so that the electrons passing through the grid around its periphery are focused onto the axis. Such a grid may find particular application to IOT-type tubes.
