空气荧光产额

The Air-Fluorescence Yield

F. Arqueros, F. Blanco, D. Garcia-Pinto, M. Ortiz, J. Rosado

摘要:

探测大范围空气簇射的带电粒子引起的空气荧光辐射是研究超高能宇宙射线的一项成熟技术。荧光望远镜提供了一种近似于量热的原始能量测量方法。目前,系统不确定性的主要来源来自我们对荧光产额的有限准确性,即由簇射粒子沉积在大气中的每单位能量发射的荧光光子的数量。在本文中,我们的知识的当前状态的荧光产额的实验和理论将进行讨论。

英文摘要:

Detection of the air-fluorescence radiation induced by the charged particles of extensive air showers is a well-established technique for the study of ultra-high energy cosmic rays. Fluorescence telescopes provide a nearly calorimetric measure of the primary energy. Presently the main source of systematic uncertainties comes from our limited accuracy in the fluorescence yield, that is, the number of fluorescence photons emitted per unit of energy deposited in the atmosphere by the shower particles. In this paper the current status of our knowledge on the fluorescence yield both experimental an theoretical will be discussed.
