Abstract
Acceleration of an externally injected electron inside the collisional plasma-filled cylindrical waveguide during its motion in the fields of the TE11 mode excited by microwave radiation is studied. The effect of the electron collision frequencywith background ions on the deflection angle and energy gain of electron, when it is injected along the direction of the mode propagation is investigated. The fields for the mode, the deflection angle of electron trajectory, due to these fields, and the electron energy gradient are obtained. The results for collisionless and collisional plasma are graphically presented. The numerical results illustrate that the presence of the electron collision term in the dielectric permittivity can reduce the electron’s energy gain in the configuration.
