    摘要: To provide an ion detector having an electron lens structure that enables expansion of an effective region of an MCP for capturing ions.The ion detector comprises an MCP unit including an MCP and a first focus electrode, a signal output device including an electron detector surface, and a reset unit disposed between the MCP unit and the signal output device. The reset unit includes a reset element and a second focus electrode. The reset element includes a second input surface and a second output surface opposing each other. On the second output surface, the reset element resets variations in incident angle and velocity of electrons on the second input surface.

    摘要: A charged particle detector according to the embodiment is provided with an MCP and a PD arranged with a focus electrode interposed therebetween in order to improve a response characteristic as compared to a conventional one in a configuration in which the MCP having a bias angle and the PD are combined. The MCP includes a plurality of through holes each inclined by a bias angle θ and the PD is eccentrically arranged such that a center of an electron incident surface deviates by a predetermined distance in a bias angle direction S3 with respect to a central axis AX1 of the MCP.
