Abstract :
In this article, we ensure low figures in microwave amplifiers of medium and high power TWT, klystrons with the compressed axial-symmetric beam. The solution of a problem on propagation of current and velocity fluctuations along the compression axial-symmetric beam in a small signal approximation taking into account a spread in velocities of electrons is presented.
