ABSTRACT:
The electron multiplier device is operable in a substantial vacuum and comprises a cathode which emits electrons upon ion bombardment and an electron multiplier section adjacent the cathode for multiplying electrons emitted from the cathode. An output target surface is partially interposed in the path of the electrons near the output of the multiplier. A portion of the electrons released by the multiplier strike the output target surface causing ions to be emitted therefrom. The ions then feed back and bombard the cathode causing it to release more electrons, which in turn are multiplied thereby providing a buildup of electrons leaving the multiplier output. The output electrons may be controlled by an electron control section aligned with the multiplier near its output end.
