Measurement and Monte Carlo Simulation of Electron Transmission Coefficient in Gas Mixtures for Plasma Display Panels

Abstract

This paper deals with the experimental and simulation results for the electron transmission coefficient in He/Xe (10%) and Ne/Xe (10%) mixtures. From the experimental results, the diffusion region, the E/p₀ dependence region and the saturation region for the electron transmission characteristic are observed in both gases. Moreover, it confirms that the electron transmission coefficient in Ne/Xe(10%) mixture becomes a higher value than that in He/Xe(10%) mixture. From the results of MCS, if the gas pressure p₀ × gap length d is the constant, even though it changes the combination of p₀ and d, it confirms that the experimental and simulation values for the electron transmission coefficient becomes equal. This means that we can compare the experimental results of the electron transmission coefficient with that of MCS. As the initial energy of the electron is large, the emitted electron is influenced by back scattering until the high reduced electric field E/p₀. Moreover, we estimates that the experimental values agree with the case that gives the initial energy distribution with the uniformity of 0 - 1.0 eV and the electron reflection coefficient of the cathode of 0.6.
