CODALEMA无线电探测实验独立天线阵的初步结果
First results of the Standalone Antenna Array of the CODALEMA Radio Detection Experiment
摘要：
CODALEMA是致力于宇宙射线无线电探测的最新领域的先驱实验之一。它位于法国南凯（Nancay）的射电天文台。直到最近，探测器的设置还结合了地面粒子探测器和覆盖总面积为0.25平方公里的有源偶极天线阵列。该实验目前正在进行重大升级，在现有设备周围部署独立天线阵列，由60个独立的新一代无线电探测站组成，覆盖面积为1.5平方公里（2011年春季部署了33个站，2011年年底将部署27个站）。这种新的设置旨在解决广泛的空气簇射无线电探测的剩余未知数，以便使这种技术成为超高能宇宙射线（UHECR）物理学的可靠和成熟的工具。最新的结果从原来的CODALEMA阵列一起讨论的独立天线阵列的第一个结果。
英文摘要：
CODALEMA is one of the pioneer experiments dedicated to the recent field of cosmic ray radio detection. It is located at the radio observatory of Nancay (France). The detector setup combined until recently a ground particle detector and an array of active dipole antennas covering a total area of 0.25 km^2. The experiment is now going through a major upgrade with the deployment around the existing apparatus of a Standalone Antenna Array, which consists of 60 standalone new generation radio-detection stations and which will cover an area of 1.5 km^2 (33 stations deployed over the spring of 2011 and 27 stations to be deployed in late 2011). This new setup is intended to tackle the remaining unknowns of extensive air shower radio detection so as to make this technique a reliable and mature tool for Ultra High Energy Cosmic Ray (UHECR) physics. The latest results from the original CODALEMA array are discussed together with the first results of the Standalone Antenna Array.
