[Class 39 (i)] A high-frequency electron discharge device comprises a cathode, anode and grid each having a length dimension many times greater than their width dimension, in combination with cavity resonators coupled between said grid and cathode and said grid and anode respectively and co-extensive in their dimensions with the electrodes. Fig. 1 shows an elongated cathode 2 heated by a heater 3 and supported by wires from a plate element 4, an anode block 7 which is an elongated plate member, and a grid 9 supported between plate-like elements 10, 11. The electrodes are mounted in a structure built up from four L-shaped elements 12, 13, 14, 15, screwed together, forming two resonant cavities. Semicircular drum-like members close the ends of the resonators, and the output is taken off by means of a coaxial line and a coupling loop. If the device is to be used as an oscillator, a loop coupling or coaxial line between the two resonators is provided. The electrodes are made concave or convex to prevent buckling under heating. In a modification of this device, the elongated electrodes comprise annular members, joined by annular cavities and enclosed in an annular envelope. In a further modification, the casing is made up of elongated U-shaped elements seated together with insulating spacers separating the electrodes and the cavity walls. The anode and cathode and their supporting resonator walls are each provided with a bored hole with which communicates a tubular lead for each electrode. In the modification shown in Fig. 6, the resonator walls extend as flat sheet-like elements 310, 312, 314 closed by sliding members 361, 362, 363, 364. Spring fingers 366, 367, 369 connected by electrodes to the resonator walls, although insulating collars 368, 370 provide the capacitative coupling for the anode and cathode. The cathode is in sections with a common heater. As shown in Fig. 10, the cathode and grid assembly may he made demountable in sections, the heater 64 being insulatingly supported on an element 404<11> to which is secured one lead 474<1>. This support rests on U-shaped elements 479, 479<1> in an insulator 478.
