CODALEMA无线电数据中地磁效应的证据

Evidence for a geomagnetic effect in the CODALEMA radio data

Benoit Revenu

摘要:

CODALEMA实验探测宇宙空气簇射的混合探测器组成的一个阵列的反射器和一个阵列的天线触发的粒子阵列。我们将首先描述实验和数据分析,然后我们将集中在天线检测到的事件的天空分布,它呈现出很强的不对称性。我们将表明,这种不对称性是很好地描述和量化的簇射电场的发射给出的簇射轴与地磁场矢量的交叉产品在一阶。这个术语的物理起源在这次会议的另一个演讲中解释。

英文摘要:

The CODALEMA experiment detects the cosmic air showers with an hybrid detector composed of an array of scintillators and an array of antennas triggered by the particle array. We will first describe the experiment and the data analysis then we will focus on the sky distribution of the events detected by the antennas which presents a strong asymmetry. We will show that this asymmetry is well described and quantified at first order by an emission of the shower electric field given by the cross product of the shower axis with the geomagnetic field vector. The physical origin of this term is explained in another talk in this conference.
