使用闪烁体空气簇射阵列来确定大范围空气簇射的方向、大小和核心位置，并使用大体积漂移室来跟踪单个簇射粒子，我们测量了海平面大范围空气簇射中带电粒子的角分布。这些分布在簇射轴线附近急剧地达到峰值，特征宽度为几度。距离簇射轴很远的粒子倾向于指向作为其原点的轴线。空气簇射的蒙特卡罗模式很好地再现了观测到的分布。
Using a scintillator air shower array to determine the direction, size, and core position of extensive air showers and a large-volume drift chamber to track individual shower particles, we have measured the angular distributions of charged particles in extensive air showers at sea level. The distributions are sharply peaked around the shower axis, with characteristic widths of a few degrees. Particles at large distances from the shower axis tend to point towards the axis as their origin. Monte Carlo models of air showers reproduce the measured distributions rather well
