Incoherent emission
WebThe incoherent emission from an undulating electron beam in the presence of metallic boundaries is analyzed. A general method of solving Maxwell's equations is used to express the field of a single particle in terms of vector waveguide modes. It is shown that the radiation characteristics depend upon a parameter involving the energy wiggler ...
