Abstract
A transition radiation interference spectrometer for measuring the energy and divergence of a charged particle beam. Transition radiation is created by placing an interferometer in the path of the charged particle beam. The resulting interference pattern is focused and masked to define an angular element at a fixed angle with respect to the direction of specular reflection. The radiation in the angular element is dispersed into wavelength components. The intensity or amplitude of the wavelength components as a function of wavelength is indicative of the beam's energy and divergence.
