Abstract
In this paper the undulator brightness and central wavelength expressions of a longitudinal wiggler magnetic field are discussed. A relativistic electron beam possessing finite perpendicular momentum introduces several transverse harmonics of motion while travelling through a longitudinally polarized wiggler magnetic field. These harmonics modulate the longitudinal electron velocity and as a consequence the radiation spectrum exhibits several harmonics.
