Abstract : The invention pertains to the class of ultrahigh frequency electrovacuum devices. The proposed amplifier makes it possible to eliminate the self-excitation and to increase the gain. This is achieved by the cross-sectional dimensions of the waveguide system smoothly (adiabatically) increasing from the middle of the wave guide to the power input and output. In this case, the intensity of the longitudinal magnetostatic field controlling the helical electron stream is smoothly reduced from the middle to the ends of the waveguide system, which is assured by a corresponding distribution of the ampereturns of the solenoid. This condition in particular is satisfied by a distribution of the solenoid field with a uniform density of the ampere turns at a specific ratio of the length of the solenoid to its diameter.
