Abstract: A scintillator includes a support substrate, an emission layer formed on the substrate, made of ZnO with impurities added to have an electron concentration of 2×1019 cm−3 or more and 2×1020 cm−3 or less, and for generating scintillation light in response to incidence of radiation, a protective layer formed on the emission layer and made of a material having a band gap wider than that of ZnO, and a metal layer formed on the protective layer. The support substrate is made of a material transmitting the scintillation light generated in the emission layer. Further, the metal layer functions as a reflection layer for reflecting the scintillation light from the emission layer.

Abstract: A mass spectrometry device includes a sample stage, an irradiator, a MCP, a fluorescent body, an imager, and a controller. The irradiator irradiates a sample with an energy beam to ionize a plurality of components of the sample while maintaining position information of the plurality of components. The MCP emits electrons in accordance with an ionized sample. The fluorescent body emits fluorescent light in accordance with the electrons. The imager has a shutter mechanism configured to be capable of switching an open state and a close state. The controller controls an opening and closing operation of the shutter mechanism. The controller allows the imager to image the fluorescent light corresponding to each of the plurality of components by performing the opening and closing of the shutter mechanism at a timing for each of the components.

Abstract: An imaging unit includes a MCP, a fluorescent body, and an imager. The MCP is provided on a flight route of an ionized sample that is a component of a sample ionized and emits electrons in accordance with the ionized sample. The fluorescent body is disposed in a subsequent stage of the MCP and emits fluorescent light in accordance with the electrons emitted from the MCP. The imager is disposed in a subsequent stage of the fluorescent body and has a shutter mechanism configured to be capable of switching an open state in which the fluorescent light is imaged by allowing the fluorescent light from the fluorescent body to pass through and a close state in which the fluorescent light is not imaged by blocking the fluorescent light from the fluorescent body. An afterglow time of the fluorescent body is 12 ns or shorter.
