摘要： A gridded electron tube suitable for generating high power at high frequency, has a cathode surface composed of a set of parallel emitting strips separated by non-emitting strips. Massive grid bars are aligned over the non-emitting strips, thereby reducing grid current interception and providing thermal dissipation. Attached to the side of the grid bars facing the cathode is an array of closely spaced fine wires which increase the electric field due to the grid at the emitting surface, and decrease the penetration of field due to the anode, thereby increasing the transconductance and amplification factor, decreasing the transit time of electrons, and improving the uniformity of emission current density.

摘要： In a controllable high-power electron tube in the form of a tetrode, the anode direct voltage is reduced to less than 10 kV with an anode efficiency of greater than 80%. The tube includes coaxially arranged electrodes including a cylindrical indirectly heated full walled matrix cathode containing BaO, a cylindrical control grid, a cylindrical screen grid and an anode, where the spacing between the control grid and the cathode and the spacing between the control grid and the screen grid is less than 1 mm. Such a tube can be used for achieving AM broadcast transmitters which are distinguished by a compact construction, the overall efficiency remaining largely unchanged.
