A method of manufacturing an electron multiplier body, the method includes a step of preparing a first plate-like member having a surface and a back surface and a pair of second plate-like members, a step of forming, in the first plate-like member, a hole portion reaching from the front surface to the back surface, a step of constituting a laminated body by laminating the first and second plate-like members on each other so that the first plate-like member is interposed between the pair of second plate-like members to form a channel defined by the hole portion in the laminated body, a step of integrating the laminated body, a step of constituting a main body portion by cutting the integrated laminated body so that the channel is open, and a step of forming a resistive layer and a secondary electron multiplication layer on an inner surface of the channel.

A device configured to convert or amplify a particle, the conversion or amplification being reliant on the impact of a particle on a surface of the device causing emission of one or more secondary electrons from the same surface. The device includes a carbon-based layer capable of secondary electron emission upon impact of a particle. The surface may be used to convert, for example, an ion into an electron signal, or an electron signal into an amplified electron signal, such as in conversion or amplification dynodes.

Components of scientific analytical equipment. More particularly, ion detectors of the type which incorporate electron multipliers and modifications thereto for extending the operational lifetime or otherwise improving performance. The ion detector may be embodied in the form of a particle detector having one or more electron emissive surfaces and/or an electron collector surface therein, the particle detector being configured such that in operation the environment about the electron emissive surface(s) and/or the electron collector surface is/are different to the environment immediately external to the detector.
