Abstract: The electron tube includes a vacuum container having a light transmitting substrate, a photocathode provided on an inner surface of the light transmitting substrate, an anode provided in the vacuum container, and a prism. The prism includes a bottom surface bonded to an outer surface of the light transmitting substrate, a light incident surface, and a light reflecting surface configured to further reflect light, which is incident to the photocathode through the prism and the light transmitting substrate and reflected at an interface between the photocathode and the vacuum space, so that the light is re-enter the photocathode. The light reflecting surface has an outwardly convex curved surface shape. The light incident surface is located inward of an imaginary spherical surface that is along the light reflecting surface.

Abstract: A photocathode 4 includes an optically transparent conductive layer provided between a translucent substrate and a photoelectric conversion layer. The optically transparent conductive layer is formed of a constituent material including carbon. A Raman spectrum of the constituent material has a peak of a band, a peak of a band, a peak of a band, and a peak of a band.

Abstract: A transmission mode photocathode comprises: an optically transparent substrate having an outside face to which light is incident, and an inside face from which the light incident to the outside face side is output; a photoelectric conversion layer disposed on the inside face side of the optically transparent substrate and configured to convert the light output from the inside face into a photoelectron or photoelectrons; and an optically-transparent electroconductive layer comprising graphene, and disposed between the optically transparent substrate and the photoelectric conversion layer.

Abstract: A photodetector assembly for ultraviolet and far-ultraviolet detection includes an anode, a microchannel plate with an array of multichannel walls, and a photocathode layer disposed on the microchannel plate. Additionally, the photocathode may include nanowires deposited on a top surface of the array of multichannel walls.
