5 Aug 2013 | | Abstract: | Tunka-Rex is the radio extension of Tunka-133, a 1 km^2 air-Cherenkov
Detector for air showers in Siberia. Tunka-Rex began operation on October 8th
2012 with 20 radio antennas. Its main goals are to explore the possible
precision of the radio detection technique in determination of primary energy
and mass. Each radio antenna station consists of two perpendicular aligned
active SALLA antennas, which receive the radio signal from air showers. The
preamplified radio signal is transmitted to local cluster centers of the
Tunka-133 DAQ, where it is filtered, amplified and digitized. To reconstruct
the radio signal it is crucial to understand how it is affected in each of
these steps. Thus, we have studied the combined response of the antenna, with
its directional pattern and the analog electronics chain, consisting of a
Low-Noise Amplifier and a filter amplifier. We discuss the hardware setup of
Tunka-Rex and how a description of its response is obtained. Furthermore, we
estimate systematic uncertainties on the reconstructed radio signal due to
hardware effects (e.g., slight variations of the electronics properties).
Finally, we present background measurements with the actual Tunka-Rex antennas. | | Source: | arXiv, 1308.0917 | | Services: | Forum | Review | PDF | Favorites | |
