Single Electron Generation and Its Imaging and Counting Using Microchannel Plate

Generation of the low energy single electron with the energy of the order of 0.1 - 1 eV and its detection with high precision are useful for the applications in the nuclear and high energy physics. Based on this situation, we have developed the compact electron generator consisting of the ultra-violet source and the target with low work function and its detection system using MCP, step by step. In order to confirm the scheme, we have developed the simple system which is composed of copper wire and Xe flash lamp as the generator and delay-line readout MCP assembly as the detector. Using this setup, we have confirmed to obtain the electron image and spectrum. To improve the system, we have developed the new electron generator consisting of UV LED and the target with lower work function and some MCP assemblies and those readout systems. In this presentation, we will report the details of the development of the single electron generator and MCP system and test results. Then the current status of the new system is described. The prospect is also presented.
