Description

The paper reports the preliminary experiment results of the electron gun based on photo-field emission of carbon nanotubes (CNTs). The quantum efficiency of the CNTs was 3.73 x 10-5 under the irradiation of the laser with wavelength of 532 nm; the peak pulse current of 3.364 A, corresponding pulse charge of 30 nC were achieved in the experiment. The relation between the photo emission current of the CNTs and the laser power under different high voltage is given. (authors)
