Abstract
An electron emitter has an emitter section formed on a substrate, a cathode electrode formed on one surface of the emitter section, and an anode electrode formed on the same one surface of the emitter section and cooperating with the cathode electrode in providing a slit. A pulse generation source applies a drive voltage between the cathode electrode and the anode electrode. The anode electrode is connected to GND (ground). The slit has a width in the range from 0.1 μm to 50 μm.
