PHOTOELECTRIC TRANSFER ELEMENT AND ELECTRON BEAM GENERATOR USING IT

摘要

PROBLEM TO BE SOLVED: To provide a photoelectric element in which damage on a photoelectric face is reduced and acceleration of electron beams is facilitated, and an electron beam generator.

SOLUTION: The transmission type cathode plug is a photoelectric transfer element of transmission type which generates electron beams in irradiation direction of laser beams by being irradiated with laser beams, and comprises a photoelectric face base substrate 302 provided with a plurality of through holes 306 along the irradiation direction and a photoelectric face 31 which is formed along the end face on the irradiation direction side of the photoelectric face base substrate 302 so as to cover the plurality of the through holes 306.
