In an inner conductor of a coaxial gyrotron, which inner conductor is disposed on the cathode of the gyrotron and includes an entrance funnel, a center part and an exit funnel, axial corrugations are formed in the conductor by axial grooves formed into its wall such that they begin at the end of the entrance funnel and have, in the center part, an increasing depths up to the exit funnel, in which the depth again becomes steadily smaller, the corrugations being evenly distributed about the inner circumference of the inner conductor.
