Abstract :
The multibeam electron flows are used in microwave tubes, such as klystrons and traveling wave tubes. Their application allows to improve operational parameters, to increase a output power without increasing of accelerating voltage, to expand a frequency pass band. For focusing of such flows the magnetic systems with a uniform or reversal fields can be used. Peculiarities of multibeam flow focusing in such systems is connected with transverse components of magnetic field originating in peripheral channels
