项目编号：ECS-9615237首席研究员：William Williamson标题：高压等离子体微放电的理论研究和数值模拟分析：将进行理论和计算研究活动，以全面了解高压等离子体微放电的物理和工程原理。该研究将为用于等离子显示面板（PDP）技术的微放电电池的开发奠定基础。PDP技术是唯一具有大屏幕潜力的平板显示技术。PDP领域目前尚未占主导地位，因此这项研究为美国的领导地位提供了一个重大贡献的机会。资助的研究活动将包括几个重要的研究：(1)气体混合物的行为；(2)利用模拟和解析理论研究多组分混合物的电压传递曲线，学习如何在给定的荧光粉响应函数下优化它们以获得最大的效率和发光输出；(3)扩充用于放电电池的稀有气体的原子数据库。（Ne， Ar和Kr）需要额外的截面。Penning电离，二聚体离子形成，中性动力学和光子跟踪（包括辐射捕获）将包括在模拟中。(4)包含三维效应，如屏障肋和不同的细胞几何形状。整体方法基于对所涉及的基本原理的仔细研究，仔细的计算设计，以准确而有效地包括许多协同等离子体，原子和固态因素，以及严重依赖与可用实验和实际电池设计策略匹配的预测。成功地开发代码来准确地模拟这些基本效果，并创建这种复杂的设计工具，将对显示技术行业具有重大价值。本研究也为强成长平板显示领域的学生提供了多学科的学习经验。

Proposal Number: ECS-9615237 Principal Investigator: William Williamson Title: Theoretical Investigation and Numerical Simulation of High Pressure Plasma Microdischarges Analysis: Theoretical and computational research activities to develop a comprehensive understanding of high pressure plasma microdischarge physics and engineering principles will be pursued. This research will form the basis for development of the microdischarge cells to be used in plasma display panel (PDP) technologies. PDP technologies are the only flat panel display technology with large screen potential. The PDP area is presently undominated, therefore this research offers an opportunity for significant contribute towards a leadership position for the United States. The grant research activities will include several important investigations: (1) the behavior of gas mixtures; (2) investigation of voltage-transfer curves for multi-component mixtures using simulations and analytic theory in to learn how to optimize them for maximum efficiencies and luminous outputs for given phosphor response functions; (3) expansion of the atomic database for the noble gasses used in discharge cells. Additional cross-sections for (Ne, Ar and Kr) are needed. Penning ionization, dimer ion formation, neutral kinetics and the tracking of photons (including radiation trapping) will be included in the simulation. (4) the inclusion of 3-dimensional effects such as barrier ribs and varying cell geometries. The overall approach is based on careful study of the basic principles involved, careful computational design to include many synergistic plasma, atomic, and solid state factors accurately yet efficiently, and a serious reliance on matching predications with available experiments and practical cell design strategies. Successful development of codes to accurately model these basic effects and to create a design tool of this sophistication will be of great value to the display technology industry. The research also provide s a multidisciplinary learning experience for students in the strong growth flat panel display area.
