Slotted microchannel plate (MCP)

摘要

A microchannel plate (MCP) (52) for an image intensifier (50) includes an active portion (62) having an input surface area for receiving electrons and an output surface area for outputting multiplied electrons. The input and output surface areas are oriented horizontally with respect to each other and spaced by a vertical distance. A non-active portion surrounds the active portion of the MCP. The non-active portion includes at least one slot (54) extending vertically into the non-active portion and extending horizontally to form a horizontal slotted area. When the MCP is positioned vertically above an electron sensing device (56) having wires (58) looping vertically above the electron sensing device, the slot is configured to receive a portion of the wires, resulting in a vertical clearance between the MCP and the electron sensing device. The wires loop a vertical looping distance above a surface of the electron sensing device, and a portion of the vertical looping distance is configured to be received within the slot of the MCP. The horizontal slotted area may be a rectangle, and the input and output surface areas may also be rectangles.
