The electron beam interference and the free electron radiation
Both electron beam interference and beat can form a periodic charge density distribution and thus a periodic electric field respectively. When another electron is moving across this field, it should irradiate electro-magnetic waves due to the acceleration. We have discussed the problems on the electron beam radiation from beat[1]. And the electron beam beat is, however, an un-usual physical phenomenon while the electron beam interference is rather common. We shall indicate here that the interference field may be used to form radiation as well.
