Caption

A structured beam of electron beamlets (modulated group of white spheres) passes through a metallic foil from left to right creating coherent optical transition radiation (COTR). This radiation encodes unique beam structure information at each wavelength, as depicted by the different red, yellow and blue radiation patterns.
