Title:
光電面電子源
Document Type and Number:
Japanese Patent JP7422035
Kind Code:
B2
Abstract:
A photoelectric-surface electron source includes: a glass substrate that receives laser light from a substrate light-receiving surface including microlenses and that focuses the laser light toward a substrate main surface located on the opposite side from the substrate light-receiving surface; a photoelectric surface that is provided to the substrate main surface, and that receives the focused laser light and emits photoelectrons; and an extraction electrode that is fixed to the substrate main surface and that extracts the photoelectrons from the photoelectric surface. The extraction electrode is disposed away from the photoelectric surface along the normal direction of the substrate main surface and has: an electrode part in which electrode holes for allowing the photoelectrons to pass therethrough are provided; and a frame part that is fixed to a region surrounding the photoelectric surface in the substrate main surface.
