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 cathode electrode and the anode electrode, and the anode electrode is connected to the ground. A collector electrode is provided above the emitter section at a position facing the slit. The collector electrode is connected to a bias voltage source through a resistor. The emitter section is made of a piezoelectric material.
