摘要:

由空气簇射发射的光的大气光的散射不仅衰减来自簇射的直接荧光,而且有助于观察到的簇射光。到目前为止,在对观测到的空气簇射光学图像进行常规分析时,只考虑了直接和单散射的切伦科夫光子。本文提出了一种计算多次散射光对光学空气簇射图像贡献的蒙特卡罗方法,并给出了模拟结果和散射光对测量的簇射信号贡献的参数化。

英文摘要:

Atmospheric scattering of light emitted by an air shower not only attenuates direct fluorescence light from the shower, but also contributes to the observed shower light. So far only direct and singly-scattered Cherenkov photons have been taken into account in routine analyses of the observed optical image of air showers. In this paper a Monte Carlo method of evaluating the contribution of multiply scattered light to the optical air shower image is presented, as well as results of simulations and a parameterization of scattered light contribution to measured shower signal.
