The motion of electrons in cylindrical magnetic field with variable strength along the axis is considered. The formation of a beam with energy of 55 keV in the longitudinal direction during its transport in solenoidal magnetic field with large gradient has been studied. The bifurcation regimes of the dynamics of particles during their movement along the transport axis both forward to the target and back to the cathode region are considered. The operating modes of the gun are obtained, in which the particle experiences the “bottleneck” effect and returns to the cathode region. It is shown that for given electron energy and fixed magnetic field, the parameter that determines the reflection of the particle is the polar angle of entry with respect to the axis of the cylindrical magnetic field. The results of numerical simulation on the motion of the electron flow are presented.
