Abstract
We report the first results from an experiment aimed at a detailed study of the interaction of an electron beam with a metallic grating (the Smith–Purcell effect). The electron beam energy was 2.3 MeV (total) and the emitted far infrared radiation was observed at emission angles in the 35–45° range. The observed signal was about 3 orders of magnitude stronger than anticipated by incoherent emission theory.
