AIRFLY测量空气荧光产额的能量依赖性

Energy Dependence of Air Fluorescence Yield measured by AIRFLY

M. Ave

摘要:

在超高能(> 10**18 eV)宇宙射线的荧光探测中,发射的荧光光子数被假定为与簇射粒子沉积在空气中的能量成正比。我们已经进行了测量的荧光产额在大气中的气体激发的电子在几个加速器的能量范围从千电子伏到数百兆电子伏。我们发现,在测量的能量范围内的比例保持在几个%的水平。

英文摘要:

In the fluorescence detection of ultra high energy (> 10**18 eV) cosmic rays, the number of emitted fluorescence photons is assumed to be proportional to the energy deposited in air by shower particles. We have performed measurements of the fluorescence yield in atmospheric gases excited by electrons over energies ranging from keV to hundreds of MeV in several accelerators. We found that within the measured energy ranges the proportionality holds at the level of few %.
