Research on Plasma Light Sources

9320515提出了选定稀土元素铥（Tm）、镝（Dy）、钬（Ho）原子跃迁概率的Lawler研究。这些元件是美国工业实验室正在开发的新一代高强度放电（HID）灯的候选产品。先进的HID灯有望提高照明效率（光效）和照明质量（显色指数）。照明消耗了美国20%到25%的电能输出。在这项提议的资助下测量的基本光谱数据对于这些新灯设计的建模和诊断是迫切需要的。威斯康星原子跃迁概率计划将扩展到这些稀土元素。自1980年成立以来，该计划不断开发和应用先进的激光和傅立叶变换技术来测量中性和单电离元素的原子跃迁概率。高效的新技术将被开发出来，以处理非常丰富和复杂的稀土光谱，同时保持在较轻元素的早期工作中获得的精度和绝对精度。与工业科学家的密切接触将贯穿整个项目。＊＊＊

9320515 Lawler Research on Atomic Transitions Probabilities for selected rare earth elements including thulium (Tm), dysprosium (Dy), and holmium (Ho)is proposed. These elements are candidates for introduction into a new generation of High Intensity Discharge (HID) lamps being developed in U.S. industrial laboratories. Advanced HID lamps have promise for improving lighting efficiency (luminous efficacy) and lighting quality (color rendering index). Lighting consumes 20 to 25% of the U.S. electrical energy output. The fundamental spectroscopic data to be measured under this proposed grant are urgently needed for modeling and diagnosing these new lamp designs. The Wisconsin Atomic Transition Probability Program will be extended to these rare earths. This program has, since its inception in 1980, continually developed and applied advanced laser and Fourier transform techniques to measure atomic transition probabilities on neutral and singly ionized elements. Efficient new techniques will be developed to deal with the very rich and complex rare earth spectra, while maintaining the precision and absolute accuracy achieved in earlier work on lighter elements. Close contact with industrial scientist will be throughout this project. ***
