Paper Abstract

This paper presents the efficiency of Smith-Purcell radiation generation for lamellar and triangular metal gratings (MG) in H-polarization. The efficiency was calculated by the modal expansion method for lamellar MG and the improved point matching method for triangular MG, respectively. Most important MG parameters involved in the calculation were: the space period, the total number of grooves, the profile and the shape of the groove, and the geometry of the reflecting surface. Calculations were performed for relativistic electron beams with energies in 1-50 MeV domains. The emission angle of coherent SP radiation depending on MG and REB parameters is also presented.
