The electric current is controlled by a bias voltage applied to the Wehnelt electrode. The combined action of the three electrodes (cathode, Wehnelt and anode) forms the crossover or the real electron source.

A Wehnelt acts as a control grid and it also serves as a convergent electrostatic lens. An electron emitter is positioned directly above the Wehnelt aperture, and an anode is located below the Wehnelt. The anode is biased to a high positive voltage (typically +1 to +30 kV) relative to the emitter so as to accelerate electrons from the emitter towards the anode, thus creating an electron beam that passes through the Wehnelt aperture.
