Research on Plasma Light Sources

9320515劳勒研究部分稀土元素的原子跃迁几率，包括Tu(Tm)、Dy(Dy)和Ho(Ho)。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(发光效率)和照明质量(显色指数)。照明消耗了美国电力输出的20%到25%。根据这项拟议的拨款，迫切需要要测量的基本光谱数据来对这些新的灯设计进行建模和诊断。威斯康星州的原子跃迁概率计划将扩展到这些稀土元素。该计划自1980年启动以来，不断开发和应用先进的激光和傅里叶变换技术来测量中性和单电离元素的原子跃迁几率。将开发有效的新技术来处理非常丰富和复杂的稀土光谱，同时保持早期在较轻元素方面取得的精确度和绝对精确度。与工业科学家的密切联系将贯穿整个项目。***

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. ***
