我们观察到的无线电横向分布的斜率之间的相关性，和59个单独的宇宙射线空气簇射事件的平均μ介子赝快度。无线电横向分布测量LOPES，一个数字无线电干涉仪与多探测器空气簇射阵列KASCADE-Grande，其中包括一个μ子跟踪探测器位于同一地点。实验证明射电测量对宇宙线空气簇射的纵向发展是敏感的。这是将射电阵列用于超高能粒子物理学和天体物理学的主要先决条件之一。
We observe a correlation between the slope of radio lateral distributions, and the mean muon pseudorapidity of 59 individual cosmic-ray-air-shower events. The radio lateral distributions are measured with LOPES, a digital radio interferometer co-located with the multi-detector-air-shower array KASCADE-Grande, which includes a muon-tracking detector. The result proves experimentally that radio measurements are sensitive to the longitudinal development of cosmic-ray air-showers. This is one of the main prerequisites for using radio arrays for ultra-high-energy particle physics and astrophysics.
