Contribution

It introduces a new antenna array prototype for radio-detection of cosmic rays and demonstrates its capability for self-triggering and initial detection in a remote environment.

Findings

Successful self-triggering on air showers achieved

First detection of extensive air showers with this prototype

Deployment in a low-noise environment enhances detection capabilities

Abstract

An antenna array devoted to the autonomous radio-detection of high energy cosmic rays is being deployed on the site of the 21 cm array radio telescope in XinJiang, China. Thanks in particular to the very good electromagnetic environment of this remote experimental site, self-triggering on extensive air showers induced by cosmic rays has been achieved with a small scale prototype of the foreseen antenna array. We give here a detailed description of the detector and present the first detection of extensive air showers with this prototype.
