摘要:

最近由CODALEMA合作的无线电探测技术的UHE宇宙线的特性的能力的演示,要求使用这种强大的方法来观察UHE中微子。为此,目前正在对现有的21厘米阵列(中国)进行调整。在一个非常低的电磁噪声水平,10160对数周期50-200兆赫天线坐落在两个高的山谷,周围的山脉。这种布局导致中微子与沿着两个4-6公里基线方向的低入射轨道相互作用的有效岩石厚度为30-60公里。我们将首次进行现场射电测量,证明这种环境对于观测源自10^17-20 eV τ中微子相互作用的τ的电磁衰变信号具有特别有利的条件。

英文摘要:

The recent demonstration by the CODALEMA Collaboration of the ability of the radio-detection technique for the characterization of UHE cosmic-rays calls for the use of this powerful method for the observation of UHE neutrinos. For this purpose, an adaptation of the existing 21CM Array (China) is presently under achievment. In an exceptionally low electromagnetic noise level, 10160 log-periodic 50-200 MHz antennas sit along two high valleys, surrounded by mountain chains. This lay-out results in 30-60 km effective rock thicnesses for neutrino interactions with low incidence trajectories along the direction of two 4-6 km baselines. We will present first in-situ radio measurements demonstrating that this environment shows particularly favourable conditions for the observation of electromagnetic decay signals of taus originating from the interaction of 10^17-20 eV tau neutrinos.
