摘要：

The generalized form of Madey's [Nuovo Cimento B 50, 64 (1979)] theorem is derived. The obtained results are used to analyze the influence of inhomogeneous electric and magnetic fields on an interaction between a beam of charged particles and a packet of electromagnetic waves. The presence of the external static fields can lead not only to the change in the damping rate of the wave packet but also to the reversal of the effect sign that is the pumping of the packet by the beam. The expression for the beam-waves energy transfer can be generalized to take into account ponderomotive forces. This interaction is illustrated by several examples: the interaction of the electron beam with Langmuir soliton, the interaction in the magnetic field with parabolic profile, and in the magnetic mirror with linear profile of the field. © 1995 American Institute of Physics.
