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. © 2001 Elsevier Science B.V. All rights reserved.
