A simulation of the generation of Smith-Purcell (S-P) radiation at terahertz frequencies is performed using the two-dimensional particle-in-cell code MAGIC. The simulation supposes that a thin (but infinitely wide), mono-energetic electron beam passes over a diffraction grating. We simulate two configurations, one similar to the Dartmouth S-P FEL, with a low-energy continuous beam (we use an axial magnetic field to constrain the electrons to essentially one-dimensional motion). The other is similar to the recent MIT experiment that uses a pre-bunched 15 MeV beam.Read less <
