Note: Consecutive capture of images of ions and electrons using high-voltage vacuum relay

Abstract:
For the first time, images of both ions and electrons appearing on a fluorescent screen attached to a micro-channel plate (MCP) [S. Nakata et al., "Applicability of micro-channel plate followed by phosphor screen to charged particles," Rev. Sci. Instrum. (submitted)] were captured in one attempt. The profile of electrostatic potential applied externally to the MCP with the fluorescent screen was quickly changed using a high-voltage vacuum relay. This method allows consecutive images of ions and electrons to be successfully captured.
