Effects of atmospheric electric fields on the evolution and radio emission of extensive air showers
Atmospheric electric fields can have an influence on the development of extensive air showers and the radio emission they emit. For the radio detection of air showers it is of vital importance to know the magnitude of this effects and the weather conditions under which it becomes significant. The physical mechanism that produces the amplified radio pulses is investigated and simulated in two st...
متن کاملMeasurement of Radio Emission from Extensive Air Showers with LOPES
A new method is explored to detect extensive air showers: the measurement of radio waves emitted during the propagation of the electromagnetic shower component in the magnetic field of the Earth. Recent results of the pioneering experiment LOPES are discussed. It registers radio signals in the frequency range between 40 and 80 MHz. The intensity of the measured radio emission is investigated as...
متن کاملPolarized radio emission from extensive air showers measured with LOFAR
We present LOFAR measurements of radio emission from extensive air showers. We find that this emission is strongly polarized, with a median degree of polarization of nearly 99%, and that the angle between the polarization direction of the electric field and the Lorentz force acting on the particles, depends on the observer location in the shower plane. This can be understood as a superposition ...
متن کاملfor extensive air showers
The new hadronic Monte Carlo model QGSJET-II is applied for extensive air shower (EAS) calculations. The obtained results are compared to the predictions of the original QGSJET and of the SIBYLL 2.1 interaction models. It is shown that non-linear effects change substantially model predictions for hadron-nucleus interactions and produce observable effects for calculated EAS characteristics. Fina...
