Abstract:
The monochromaticity of the Smith-Purcell optical radiation generated by a 75-keV electron beam with a final emittance of ε = 0.65 × 10−4 mm rad that passes over a grating with a period of D = 0.833 μm has been analyzed. It has been shown that the monochromaticity of Smith-Purcell radiation is determined not only by the angular aperture of a monochromator but also by the divergence of the electron beam.
