| Abstract(in English) | Smith-Purcell(SP) radiation was generated at wavelengths of 350-750 nm in an experiment using a field-emitter array(FEA) cathode. The electron gun was 5 cm long and a 25 mm x 25 mm replica grating was placed behind the slit provided in the anode. The grating had a 0.556μm period, 30° blaze angle and a 0.2μm thick aluminum coating. The highest energy and current of the electron beam were 60 keV and 25μA, respectively. Spectral characteristics of the radiation were measured automatically, the spectrometer was driven by a stepping motor to scan the wavelength and A/D-converted signals from a photomultiplier tube were processed by a personal computer. The measurements, made at 80° with respect to the electron beam, showed good agreement with the theory of SP radiation. Recently we have started an experiment on photoelectric field emission, illuminating FEAs with a 100 mW cw YAG laser(2ω_0). Preliminary results on the enhancement of electron emission are also reported in this paper. |
