Development of a single-shot charge state analyzer for laser produced plasmas

This paper reports on the development of a single-shot charge state analyzer, which enables us to observe plasma ion flux waveforms for various charge states simultaneously by separating the ion flux for each charge state. The analyzer was carefully designed to suppress the space charge effect and eliminate electrons from the plasma with the help of numerical analyses such as a beam envelope calculation. From the beam spot observation using a MCP assembly, we confirmed that the plasma ion flux was separated into multi beams depending on the charge state of the ions. (author)
