    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.

    Abstract: A high-energy ray detector includes a detection unit in a vacuum container. The detection unit includes a first electron multiplier, a second electron multiplier, and an electron collector. Each of the first electron multiplier and the second electron multiplier has one or more MCPs each configured to emit electrons by interaction with an incident high-energy ray (γ-ray, X-ray (in particular hard X-ray), or neutron ray), and multiply and output the electrons. The electron collector is transmissive for the high-energy ray. The electron collector is configured to collect the electrons multiplied and output from each of the first electron multiplier and the second electron multiplier, and output an electric pulse signal.
