Abstract
An electron emitter has an emitter section formed on a substrate, and a cathode electrode and an anode electrode formed on a same surface of the emitter section. A slit is formed between the cathode electrode and the anode electrode. A drive voltage from a pulse generation source is applied between the anode electrode and the cathode electrode. The anode electrode is connected to the ground. A charging film is formed on a surface of the anode electrode.
