Abstract

An ion detector 7 for a mass spectrometer is disclosed comprising a microchannel plate 8 which receives ions 12 at an input surface and releases secondary electrons 16 from an output surface. A detecting device 9 having a detecting surface is arranged to receive at least some of the electrons 16 emitted by the microchannel plate 8. The area of the detecting surface is substantially greater than the area of the output surface of the microchannel plate 8.
