Coherent Transition Radiation from Bunches of Charged Particles

Form factors for bunches of charged particles largely determine the characteristics of the emitted coherent radiation. Transition radiation is emitted when a charged particle passes through an inhomogeneity such as a boundary between two different media. In this Demonstration, the boundary is between a vacuum and a metal target with infinite electrical conductance. The form factor can be used to determine the output radiation spectra, a solution of the inverse problem of determining the configuration of the charged particle beam from the emitted radiation.
