anode

anode

An electrode, to which a positive potential (voltage) is applied against the facing cathode (electron source). The "anode" receives the flow of electrons (electron beam) emitted from the cathode, and guides the electron flow downward through the hole at its center. In the case of a six-stage acceleration of 200 kV, the voltage applied to the anode is ~33 kV against the cathode.
