Abstract (en)
[origin: FR2775118A1] The invention concerns an electronic tube grid with axial beam (50), comprising an open-worked part (23) designed to be traversed by the beam (50) electrons. The grid is shaped like a bell (22) and is made of a single material. The open-worked part (23) is located at the bell top (21) but is placed at the base of a hollow part so that the electrons passing through the grid at its periphery are focused on the axis. The invention is particularly applicable to IOT.
