基于荧光数据的大范围空气簇射的三维重建

3D Reconstruction of Extensive Air Showers from Fluorescence Data

S. Andringa, M. Pato, M. Pimenta

摘要:

提出了一种重建荧光探测器所看到的广泛空气簇射三维结构的新方法。对于连续的时间仓,在二维像素中完成对簇射的观察。时间相当于第三个维度。假设宇宙射线簇作为以光速移动的平面波前传播,空间中的复杂3D体积可以与每个测量的电荷(每个像素和时间仓)相关联。空间中的3D描述允许同时访问每个淋浴的纵向和横向轮廓。在几只眼睛观察同一个淋浴的情况下,该方法给出了所有信息的直接组合。该方法处于早期开发阶段,不用于俄歇数据的一般重建。

英文摘要:

A new method to reconstruct the 3-dimensional structure of extensive air showers, seen by fluorescence detectors, is proposed. The observation of the shower is done in 2-dimensional pixels, for consecutive time bins. Time corresponds to a third dimension. Assuming that the cosmic ray shower propagates as a plane wave front moving at the speed of light, a complex 3D volume in space can be associated to each measured charge (per pixel and time bin). The 3D description in space allows a simultaneous access to the longitudinal and lateral profiles of each shower. In the case that several eyes observe the same shower, the method gives a straight-forward combination of all the information. This method is in an early phase of development and is not used for the general reconstruction of the Auger data.
