KHARLASHKIN The influence of the assumed klystrons’ coaxiality location in an orientation “cathode leg to the cathode leg” at the value of the distances between the klystrons’ cathode legs are no less than a 0,03 m on the magnetic field of the devices, and also the ferromagnetic material at a location in the distance no less than a 0,05 m from the klystron‘ magnetic system has been investigated in this paper. One of the klystrons works in the output poweramplifier stages of the electric vacuum device’s chainlets in the channel of the sublight of the aim, which is placed in the selfpropelled zenithal-rocket options. Key words: the coaxiality locations, the ferromagnetic material, the amplitude of the magnetic field, the electronic beam. E-mail: strukovw1@mail.ru. Pp. 47-50
