Abstract

The stopping power of ion barrier films (IBFs) of Microchannel Plate (MCP) in Generation III image tubes for incident positive ions was described in this paper. Nuclear Stopping Power, Electronic Stopping Power and Mean Range were introduced. These concepts were analyzed and discussed, combined with Tomas-Fermi shielding potential. The results of a Monte Carlo simulation on Nuclear Stopping Power, Electronic Stopping Power and Mean Range were also presented when the ions with different energies were perpendicularly incident to Al₂O₃ and SiO₂ films. The results indicate that the stopping power of Al₂O₃ film is stronger than that of SiO₂, and the selection of Al₂O₃ is reasonable and feasible.
