LOPES 3D -- studies on the benefits of EAS-radio measurements with vertically aligned antennas
D. Huber, W. D. Apel, J. C. Arteaga-Velazquez +54
The LOPES experiment was a radio interferometer built at the existing air shower array KASCADE-Grande in Karlsruhe, Germany. The last configuration of LOPES was called LOPES 3D and…
A comparison of the cosmic-ray energy scales of Tunka-133 and KASCADE-Grande via their radio extensions Tunka-Rex and LOPES
W. D. Apel, J. C. Arteaga-Velázquez, L. Bähren +73
The radio technique is a promising method for detection of cosmic-ray air showers of energies around PeV and higher with an array of radio antennas. Since the amplitude of t…
Revised absolute amplitude calibration of the LOPES experiment
K. Link, T. Huege, W. D. Apel +54
One of the main aims of the LOPES experiment was the evaluation of the absolute amplitude of the radio signal of air showers. This is of special interest since the radio technique…
Investigation of the radio wavefront of air showers with LOPES measurements and CoREAS simulations (ARENA 2014)
F. G. Schröder, W. D. Apel, J. C. Arteaga-Velazquez +54
We investigated the radio wavefront of cosmic-ray air showers with LOPES measurements and CoREAS simulations: the wavefront is of approximately hyperbolic shape and its steepness i…
First Experimental Characterization of Microwave Emission from Cosmic Ray Air Showers
R. Smida, F. Werner, R. Engel +55
We report the first direct measurement of the overall characteristics of microwave radio emission from extensive air showers. Using a trigger provided by the KASCADE-Grande air sho…
Reconstruction of the energy and depth of maximum of cosmic-ray air-showers from LOPES radio measurements
W. D. Apel, J. C. Arteaga-Velazquez, L. Bähren +53
LOPES is a digital radio interferometer located at Karlsruhe Institute of Technology (KIT), Germany, which measures radio emission from extensive air showers at MHz frequencies in…
