ABSTRACT:
The invention relates to secondary-emissive microchannels which are bent to a given extent on the output side of the electrons. The said bending serves to restrict the areas where the electrons contact the channel walls to a small zone at the end of the electron multiplication and before the departure of the secondary electrons. The energy of the output electrons is thus dispersed very little.
The emission of electrons can then be controlled by means of low electrical voltages which can be readily switched. The said partially curved microchannels are incorporated in electron tubes in the advantage of the ease of control, is utilized.
