We have been studying on muon beam quality improvement by moderating generated by an accelerator with a thin Si film, and then decelerating and focusing the beam in an electrostatic field. In this study, numerical simulation of an experiment in which of a few MeV is injected into a 0.5~mm thick Si plate and , which is decelerated to a few keV, is extracted electrostatically is performed using charged particle orbit software (SIMION). The flight time to the end of the transport tube and the transport efficiency change with a slight shift of the muon launch position, suggesting that the muon transport process is sensitive to the initial conditions.
