1. High-power electron tube in particular for high-frequency applications, with a coaxial electrode arrangement, with an inner heatable cathode (7) being surrounded by an outer anode (4) and the cathode (7) exhibiting in coaxial arrangement an inner conductor (9) and an outer conductor (8), between which a cathode space (16) is present, characterized in that for damping undesired natural oscillations within the tube in the cathode space (16) there is arranged a damping construction (10) surrounding the inner conductor (9) and arranged coaxially to the electrodes, and in that the specific electric resistance of the damping construction (10) at room temperature lies between 100 and 10,000 OMEGA. mu m, preferably between 800 and 3,000 OMEGA. mu m. |
