Title:
撮像ユニット、質量分析装置、及び質量分析方法
Document Type and Number:
Japanese Patent JP7424578
Kind Code:
B2
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.
