摘要： An electron multiplier that can easily obtain characteristics according to a purpose is provided. By bonding a marginal portion 23 of an MCP 2 and a marginal portion 33 of an MCP 3 to each other via a conductive spacer layer 7, a gap 12 is formed between channel portions 22, 32. Therefore, when the electron multiplier is used for a purpose that requires a particularly high gain, by adjusting the thickness of the spacer layer 7, the gain can be increased by increasing the gap 12. In addition, when the electron multiplier is used for a purpose that requires an increase in gain as well as time characteristics, by adjusting the thickness of the spacer layer 7, the size of the gap 12 can be adjusted so that desired characteristics are obtained. Consequently, by only adjusting the thickness of the spacer layer 7, characteristics according to the purpose can be easily obtained.

摘要： A mass spectrometer that allows easy replacement of an MCP (microchannel plate) and is enabled to secure orthogonality between an incident surface of the MCP and an ion track at high accuracy is provided. A flight tube 2 where ions fly is arranged in a vacuum vessel composed of a vacuum flange 6 and a body 1, and an MCP group 4 is attached to a tail end of the flight tube 2 via an MCP-IN electrode 3. A vacuum flange 6 is attachably and detachably attached to the body 1, and the MCP group 4, by a spring 710 provided on a circuit board 7 for detection attached to the vacuum flange 6, is urged toward an end portion of the flight tube 2 so that its orthogonality with respect to an ion flight track is secured.

摘要： An MCP has a rectangular plate shape and has a porous part, to which a plurality of pores (channels) penetrating in the thickness direction are disposed, and a poreless part including a solid glass or the like to which the channels are not provided on the both sides of the porous part. Then, on both surfaces of the MCP, an input side electrode and an output side electrode are respectively formed so as to cover the poreless parts on the both surfaces while sandwiching the porous part.
