Abstract
An electron multiplier is formed between two spaced parallel substrates of electrically conductive material with a cathode at one end of the substrates. On opposed surfaces of the two substrates are dynodes, extraction electrodes, modulation electrodes, electrically conductive protrusions and deflection electrodes in that order going away from the cathode end. The dynodes form a conventional staggered dynode chain. The modulation electrode on one substrate is opposite a modulation electrode on the other substrate and both have a width equal to the distance between the substrates. The protrusions are similarly directly opposite one another. At the end of the substrates remote from the cathode is a deflection electrode on the tip of each substrate.
