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.
