Abstract
An electron emitter has an electric field receiving member formed on a substrate, and a cathode electrode and an anode electrode formed on a same surface of the electric field receiving member. A slit is formed between the cathode electrode and the anode electrode. The cathode electrode is supplied with a drive signal from a pulse generation source, and the anode electrode is connected to an anode potential generation source (GND in this example). A charging film is formed on a surface of the anode electrode.
Claims17
An electron emitter comprising:
- an electric field receiving member made of a dielectric material;
- a cathode electrode to which a drive signal is supplied, said cathode electrode being formed in contact with said electric field receiving member;
- an anode electrode formed in contact with said electric field receiving member, wherein
- a slit is formed between said cathode electrode and said anode electrode;
- and
- a charging film is formed at least on a surface of said anode electrode.
