Abstract: PROBLEM TO BE SOLVED: To provide a phosphor which emits fluorescence corresponding to incident electrons.
SOLUTION: An electron beam detector is integrated with a compound semiconductor substrate and an optical detector by optically connecting the fluorescence emitting surface of the compound semiconductor with a light incident surface of the optical detector using a light guide, and physically connecting the compound semiconductor substrate and the optical detector. The incident electron ray is detected such that the compound semiconductor substrate converts the incident electrons to the fluorescence, the light guide transmits the fluorescence to the optical detector, and the optical detector detects the fluorescence. Therefore, the incident electron rays are detected.

Abstract: PROBLEM TO BE SOLVED: To provide a practical electron multiplier element which can be manufactured at low cost, and an electron multiplier device using the same.
SOLUTION: The electron multiplier element 9 comprises a phosphor 12 emitting light by dint of kinetic energy of an accelerated electron injected, a support 11 transmitting the light from the phosphor 12 supporting the phosphor 12 at a surface 11a and emitting light from a surface 11b, and a photoelectric surface 13 converting the light of the phosphor 12 supported by the surface 11b. The phosphor 12 and the photoelectric surface 13 are arranged so that the number of electron emitted from the photoelectric surface 13 exceeds the number of electron incident onto the phosphor 12. The electron multiplier element converts electron into light and converts the light into electron thereafter. By the above, a practical electron multiplying function can be realized while imposing a thickness on the support 11. The manufacturing cost of the electron multiplier element 9 can be lowered by far in comparison with an MCP because of its simple structure.

Abstract: PURPOSE:To prevent fixed pattern noise from being produced by allowing a YAG crystalline plate provided so that an incoming surface for an electron is in opposite to the photoelectric surface of an input surface plate to function as a fluorescent screen and an outgoing surface. CONSTITUTION:An incident light image converged upon an input surface 20 by a lens system 50 is converted into photoelectrons with a photoelectric surface 21 formed in the input surface 20. Photoelectrons produced from the photoelectric surface 21 are led to MCP 70. Photoelectrons multiplied by MCP 70 are led to the inner surface 30a of an output surface plate 30. The inner surface 30a which is a fluorescent screen emits light by photoelectrons and an output light image corresponding to the incident light image is produced as an optical image in the inner surface 30a. The output light image produced in the inner surface 30a passes through the output surface plate 30 and is emitted from an external surface 30b. Thus, since the fluorescent screen is formed in one body with the output surface plate, fixed pattern noise is not produced when light is emitted in the incoming surface for an electron.
