Tues AM II - Air Shower Experiment
The Tunka-Rex experiment (Tunka Radio Extension) was created in 2012 at the Tunka Valley (Republic of Buryatia, Russia). Its purpose is to investigate methods for the energy spectrum and the mass composition of high energy cosmic rays based on the radio emission of air showers. Tunka-Rex is an array of 25 radio antennas distributed over an area of 3 km2. The most important feature of the...

Tues AM II - Air Shower Experiment
Microwave radiation from high-energy air showers has been observed in the C band (3.4–4.2 GHz) with the Cosmic-Ray Observation via Microwave Emission (CROME) setup. The obtained dataset provides a unique opportunity to study the radio emission of air showers at microwave frequencies. The compatibility of the measured GHz signals with different hypotheses for the emission mechanism is...

Tues AM II - Air Shower Experiment
Observations of microwave radiation emitted by low energy electrons left after the passage of a high energy electron beam in accelerator experiments offered new possibilities of Ultra High Energy Cosmic Rays (UHECR) detection techniques based on microwave radiation. This would bring a tenfold increase in detector duty cycle compared to the standard fluorescence technique.
The emission...

Tues AM II - Air Shower Experiment
The code SELFAS computes the electric field emitted by the secondary electrons and positrons in air showers initiated by high-energy cosmic rays.
SELFAS is based on the shower universality. We will focus on the main successes of the code to explain observations in the range MHz-GHz, and we will insist on the signal emitted by the sudden death of air showers when the front disappear in the...
