ABSTRACT:
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.
