Outline of Final Research Achievements

The goal of this study is to establish the basic technology of single electron production in vacuum and its imaging. In addition to the goal, the system is used for proof-of-principle of electric field measurement. Slow electron can be obtained by special material irradiated with the ultra-violet photon, which is known as photoelectric effect. Imaging such electron is done with a special detector system (MCP). This scheme has been developed. It is known that imaging rate changes with the voltage of target material by our studies. We have challenged the proof-of-principle of electric field measurement using this phenomenon, We have succeeded in the electron imaging and promoted the improvement of the detector system and target material. Detailed investigation and the challenge of electric filed measurement is still remaining, then those will be performed.
