用LOPES无线电天线阵测量空气簇射

Air Shower Measurements with the LOPES Radio Antenna Array

A. Haungs

摘要:

LOPES建立在德国卡尔斯鲁厄的KASCADE-Grande广泛空气簇射实验的位置,旨在测量和研究广泛空气簇射的无线电脉冲。由于无线电波的衰减很小,无线电测量可以探测到非常远或高度倾斜的阵雨。这些波可以日夜记录,并提供轻子簇射分量的辐射热测量。LOPES被设计成一个数字射电干涉仪,使用高带宽和快速数据处理,并受益于KASCADE-Grande的重建空气簇射观测值。LOPES天线经过绝对幅度校准,可以重建电场强度,并与详细的蒙特卡罗模拟预测进行比较。我们报告的相关性分析存在的无线电信号测量的LOPES 30天线阵列。此外,LOPES还操作不同类型的天线(LOPES-STAR),这些天线针对皮埃尔俄歇天文台的应用进行了优化。讨论了LOPES的现状、数据分析的最新结果和进一步的发展前景,以及这种新的探测技术可能的大规模应用。

英文摘要:

LOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from Extensive Air Showers. Since radio waves suffer very little attenuation, radio measurements allow the detection of very distant or highly inclined showers. These waves can be recorded day and night, and provide a bolometric measure of the leptonic shower component. LOPES is designed as a digital radio interferometer using high bandwidths and fast data processing and profits from the reconstructed air shower observables of KASCADE-Grande. The LOPES antennas are absolutely amplitude calibrated allowing to reconstruct the electric field strength which can be compared with predictions from detailed Monte Carlo simulations. We report about the analysis of correlations present in the radio signals measured by the LOPES 30 antenna array. Additionally, LOPES operates antennas of a different type (LOPES-STAR) which are optimized for an application at the Pierre Auger Observatory. Status, recent results of the data analysis and further perspectives of LOPES and the possible large scale application of this new detection technique are discussed.
