与Cosmic-Ray检测相关的空气荧光--第五届荧光研讨会总结,El Escorial 2007

Air Fluorescence Relevant for Cosmic-Ray Detection - Summary of the 5th Fluorescence Workshop, El Escorial 2007

Fernando Arqueros, Joerg R. Hoerandel, Bianca Keilhauer

摘要:

能量超过$10^{17}$ eV的高能宇宙射线经常通过测量由空气簇射引起的荧光来观测。这种实验的绝对能量尺度的系统不确定性的一个主要贡献是对空气中电子的荧光产额的知识不足。第五届荧光研讨会的目的是汇集实验和理论专业知识,讨论荧光产额研究的最新进展。将审查讲习班的成果以及这一领域的知识现状。重点是给出了重要的空气簇射观测和它的依赖于大气参数,如压力,温度和湿度的荧光产量。将讨论最新结果对从空气簇射观测到的光的影响。

英文摘要:

High-energy cosmic rays with energies exceeding $10^{17}$ eV are frequently observed by measurements of the fluorescence light induced by air showers. A major contribution to the systematic uncertainties of the absolute energy scale of such experiments is the insufficient knowledge of the fluorescence light yield of electrons in air. The aim of the 5th Fluorescence Workshop was to bring together experimental and theoretical expertise to discuss the latest progress on the investigations of the fluorescence light yield. The results of the workshop will be reviewed as well as the present status of knowledge in this field. Emphasis is given to the fluorescence light yield important for air shower observations and its dependence on atmospheric parameters, like pressure, temperature, and humidity. The effects of the latest results on the light observed from air showers will be discussed.
