Abstract

Some of the effects in a weak focusing magnetic field are considered and the degrees of their influences are estimated in the report. The effects are divided into three groups. The first one is connected with fast cyclotron waves, the second--with the process of electron beam formation and the third--with the collecting of electrons. It is shown that the operating backward electromagnetic wave and the extracting forward electromagnetic wave, which extracts the microwave energy from the interaction space, have the difference in the process of reradiation into cyclotron waves. The report includes results of calculation of the equations together with the deduction of those equations. The influence of decompression on the BWO operation driven by weakly magnetized electron beam is explained. The results of experiments with the specially elaborated model are presented. The last problem is connected with virtual cathode that can appear in the collector region and reflect back the electrons. The influence of the reflected electrons is estimated.
