    摘要: In a conventional micro-channel plate (MCP), a secondary electron (SE) detector or a semi-conductor detector the number of the electrons is amplified through its own structure. For such amplification a small voltage difference is applied externally or generated due to its own structure and material. The electric current of electrons undergoing the above-described procedure is amplified by an external amplification circuit. In the present invention electrons—resulting from the collision of the electron beam generated by a microcolumn—are detected by surrounding conductive wiring. The detected electrons are amplified using an amplification circuit on the outside similar to a conventional detection method.

    摘要: To miniaturize a secondary-electron detector, a ring-shaped secondary-electron emissive material layer 44A is formed on a ring-shaped base 41 having a round hole 41a, via a ring-shaped insulating layer 42A and a ring-shaped high resistance layer 43A. Similarly, a ring-shaped secondary-electron emissive material layer 44B is formed on a ring-shaped base 33 having a round hole 33a, via a ring-shaped insulating layer 42B and a ring-shaped high resistance layer 43B. A arc-shaped multiplied-electron collecting electrode 461 is joined between the insulating layers 42A and 42B outside the secondary-electron emissive material layer 44B. A porous secondary-electron multiplication substance may be filled between opposed bases instead of the secondary-electron emissive material layers 44A and 44B, and an optical fiber coated with phosphor may be used instead of the electrode 461.
