“…Provided that the unblinded data confirm that the Tunka-Rex precision is indeed comparable to the Tunka-133 precision, then the radio technique qualifies for its application to cosmic-ray science. For this purpose, Tunka-Rex has already been extended by deploying additional antennas, which will be triggered by the new scintillator array Tunka-Grande at the same site [15]. Using the scintillators as trigger during day-time and bad-weather periods, Tunka-Rex can significantly increase the statistics around 10 18 eV, which is exactly the energy range for which the present Tunka-133 analyses is limited by statistics.…”

The Tunka observatory is located close to Lake Baikal in Siberia, Russia. Its main detector, Tunka-133, is an array of photomultipliers measuring Cherenkov light of air showers initiated by cosmic rays in the energy range of approximately 10 16 − 10 18 eV. In the last years, several extensions have been built at the Tunka site, e.g., a scintillator array named Tunka-Grande, a sophisticated air-Cherenkov-detector prototype named HiSCORE, and the radio extension Tunka-Rex. Tunka-Rex started operation in October 2012 and currently features 44 antennas distributed over an area of about 3 km 2 , which measure the radio emission of the same air showers detected by Tunka-133 and Tunka-Grande. Tunka-Rex is a technological demonstrator that the radio technique can provide an economic extension of existing air-shower arrays. The main scientific goal is the cross-calibration with the air-Cherenkov measurements. By this cross-calibration, the precision for the reconstruction of the energy and mass of the primary cosmic-ray particles can be determined. Finally, Tunka-Rex can be used for cosmic-ray physics at energies close to 1 EeV, where the standard Tunka-133 analysis is limited by statistics. In contrast to the air-Cherenkov measurements, radio measurements are not limited to dark, clear nights and can provide an order of magnitude larger exposure.

“…A final verification of precise and stable timing operation is the full reconstruction of cosmicray air showers, registered in routine operation with HiS-9 for 2013/14 and HiS-28 (2014/15; in progress). Using the calibration from LED runs, reconstruction of the shower front direction and position is done for HiS-9 [2,8]. Figure 9 displays a reconstructed shower event (based on WRtiming only); the fitted time-residual distribution indicates an upper limit for σ W R of <0.5 ns [8].…”

Upcoming Gamma-Ray and Cosmic-Ray experiments require relative time calibration of all detector components with (sub-)nanosecond precision. White Rabbit, a new technology for time and frequency transfer, can be applied here. We describe a White Rabbit (WR) based design for trigger time-stamping, originally developed for Tunka-HiSCORE -a timing array for Gamma-Ray astronomy now under construction. Subnsec synchronization results from cosmic ray shower data, in-situ artifical light source calibrations and laboratory tests taken over several years are presented.
