| 英文摘要 | TREND50 is a radio detection setup of 50 self-triggered antennas working in the 50-100 MHz frequency range and deployed in a radio-quiet valley of the Tianshan mountains (China). TREND50 achieved its goal: the autonomous radiodetection and identification of air showers. Thanks to a dedicated offline selection algorithm, 564 air shower candidates were indeed selected out of 7 . 10(8) transient radio signals recorded during the 314 live days of data taken during the first two years of operation of this setup (2011 and 2012). This event rate, as well as the distribution of the candidate directions of arrival, is consistent with what is expected from cosmic-ray-induced air showers according to simulations, assuming an additional similar to 20% contamination of the final sample by background events. This result is obtained at the cost of a reduced air shower detection efficiency, estimated to be similar to 3%. This low efficiency is mostly due to the large amount of dead time of the setup. This result paves the way for the GRANDProto35 experiment, the first stage of the GRAND project. (C) 2019 Elsevier B.V. All rights reserved. |
