摘要： A method of emitting electrons by applying a voltage between a voltage application electrode and a target to be irradiated with the electrons emitted from an electron emission electrode with a conical portion in an electron emission device. The voltage application electrode is formed to oppose the electron emission electrode so as to sandwich an insulating layer therebetween and the target. A charge of the electron emission electrode which is lost by electron emission during an electron emission operation is supplied after the electron emission operation is completed.

摘要： A measuring system particularly suitably usable with an apparatus having a plurality of electron emitting sources, for measuring the characteristics of the electron emitting sources is disclosed. In the measuring system, the electron emitting sources are driven so that they emit electron flows of predetermined and different frequencies. The emitted electron flows are collected and, thereafter, only those signals having components corresponding to the predetermined frequencies are extracted. Based on the extracted signals, the characteristics of the electron emitting sources are measured at the same time and independently of each other.
