Air shower universality from 1014to 1022eV

Applying Shower Development Universality to KASCADE Data

On basis of the theorem of a universal shower development stating that a hadronically generated extensive air shower is completely described by the primary energy, the position of the shower maximum and a parameter related to the total muon number, the so-called correlation curve method is developed and applied to KASCADE data. Correlation information of the muon and electron content of showers...

KASCADE extensive air shower experiment

The main aim of the KASCADE extensive air shower (EAS) experiment is the determination of the chemical composition of cosmic rays in the energy range around and above the knee at Ek ≈ 3 PeV. A large number of observables is measured simultaneously for each individual event, by the combination of various detection techniques for the electromagnetic, the muonic, and the hadronic component of the ...

Air Shower Measurements with LOFAR

Air showers from cosmic rays emit short, intense radio pulses. LOFAR is a new radio telescope, that is being built in the Netherlands and Europe. Designed primarily as a radio interferometer, the core of LOFAR will have a high density of radio antennas, which will be extremely well calibrated. This makes LOFAR a unique tool for the study of the radio properties of single air showers. Triggering...

Cosmic Ray Results from the IceTop Air Shower Array

IceTop, the surface component of the IceCube neutrino telescope at the South Pole, is an air-shower array which will finally consist of 160 ice Cherenkov tanks at 80 stations spread over an area of 1 km. Currently 40 stations are deployed and taking data. The detector is designed to cover the energy range above the knee up to about 10 eV and study the mass composition of primary cosmic rays. In...
