Interference effects in undulator and wiggler radiation sources

Abstract A simple model is described that is useful in understanding the spectral and angular properties of the radiation emitted in periodic undulator and wiggler magnets. Detailed comparisons with exact calculations show that it is also sufficiently accurate to be used for practical computations. An extension of the model allows the major effects of field errors to be simulated in a simple way.
