U.S.-Germany Cooperative Research: Microhollow Cathode Discharge Excimer Lamps

这是对美国国家科学基金会奖INT-9726752的一年续订，以支持卡尔·舍恩巴赫博士和一名博士后与埃尔兰根弗里德里希·亚历山大大学物理系的克劳斯·弗兰克合作。合作将研究两个主题：稳态阶段多个平行放电的物理，以及放电点火过程。这些研究对开发直流低压平板灯具中的准分子光源具有一定的应用价值。关于直流放电的实验和建模研究将与Erlangen的点火阶段研究相结合，以加快平板准分子灯领域的研究，该领域提供了具有广泛应用的准单色光源。总体而言，这两项工作将有助于更好地了解空心阴极放电阵列的物理原理，提供有关单个空心阴极放电和放电阵列中的电击穿的信息，并确定电极材料和介质对微空心阴极放电性能的影响。

0001438SchoenbachThis is a one-year renewal to NSF award INT-9726752 to support Dr. Karl Schoenbach and a postdoctoral student to collaborate with Klaus Frank of the Physics Departent at the Friedrich Alexander University in Erlangen. The collaboration will study two topics: the physics of multiple, parallel discharges in the steady-state phase, and the discharge ignition process. These studies have application to the development of excimer light sources in direct-current (DC), low-voltage, flat-panel lamps. Experimental and modeling studies on DC discharges will be combined with ignition-phase studies at Erlangen to accelerate research in the area of flat-panel excimer lamps, which provide quasi-monochromatic light sources with a wide range of applications. Overall, the combined effort will provide a better understanding of the physics of hollow-cathode discharge arrays, provide information on the electric breakdown in single hollow-cathode discharges and discharge arrays, and determine the effect of electrode materials and dielectrics on the performance of the microhollow cathode discharges.
