Abstract
A particle detector for an electron microscope, a mass spectrometer or the like comprises a single flat plate electron multiplier such as a micro-channel plate or a micro-sphere plate followed by a scintillator. The use of the electron multiplier prior to the scintillator compensates for lack of efficiency in passing photons from the scintillator. The output voltage of the scintillator can be freely set.
