The physical mechanism we are going to describe for the coherent emission by an electron beam has three separate phases. In the first, the beam with an initial uniform charge density is energy modulated; in the second this modulation is transformed into a density modulation; in the last phase the coherent bunched beam interacts with the static magnetic field of a wiggler (for the spontaneaous coherent emission) or with a potential pattern build up by an external electromagnetic wave travelling with the EB and the static periodic magnetic field (for the stimulated coherent emission).
