ABSTRACT:
An electron multiplier according to this invention comprises dynodes DY1 .about.DY16 arranged in multi-stages along a direction of incidence of an energy beam for, upon incidence of the energy beam, gradually multiplying secondary electrons to emit the same, a collection electrode A for receiving electrons emitted from that of the dynodes on a last stage, and resistors R1 .about.R16 inserted between the respective dynodes and their adjacent ones, the dynodes, the collecting electrode, and the resistors being mounted between two support plates 10a, 10b disposed in parallel with each other, the resistors being arranged in two rows which sandwich the dynodes.
