Charged particle detector

A charged particle detector comprising:

• a microchannel plate having an input surface having charged particles input thereon, a multiplication portion performing multiplication of electrons based on an input of the charged particles while maintaining positional information of the charged particles with respect to the input surface, and an output surface outputting electrons multiplied by the multiplication portion;
• a multi-dynode having a plurality of dynodes multiplying the electrons output from the output surface, and insulation regions positioned between the dynodes;
• and
• an anode disposed in a spatial region between the output surface and the multi-dynode, and having collection portions for collecting electrons multiplied by the dynodes and aperture portions for allowing electrons output from the output surface to pass therethrough to the multi-dynode side,
• wherein all of the insulation regions overlap the collection portions when viewed in an output direction of the electrons from the output surface.
