Research Abstract

The goal of this study is development of the basic technology to produce a single electron in vacuum and to have imaging of its electron. It is well known that a material which has a threshold (work function) emit an electron when the material is irradiated with a photon which has an energy larger than the threshold. This phenomenon is used in this study. The copper irradiated with the ultra-violet photon can be considered to emit single slow electron in vacuum. A special detector (MCP) is used for the imaging of slow electrons in vacuum. We have developed new system using those and seemed to succeed in the single electron imaging. Detail investigation is not done yet, then will be performed.
