ION DETECTION DEVICE AND ION DETECTION METHOD

WIPO Patent Application WO/2010/125670

A1

Provided is an ion detection device comprising a mechanism for converting ions into electrons and amplifying the electrons obtained by the conversion, which enables a reduction in noise caused by stray light. The ion detection device is provided with an ion-electron conversion electrode which converts mass-fractionated ions into electrons, and an amplification mechanism which is configured so as to amplify the electrons, the amplification mechanism leading the electrons obtained by the conversion by the ion-electron conversion electrode thereinto by an electric field and amplifying the electrons.  The ion-electron conversion electrode has any one of a needle shape, a ribbon shape, a mesh shape, or a slit shape.
