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...

The Extensive Air Shower Experiment Kascade - First Results

The extensive air shower (EAS) experiment KASCADE has started its operation at the laboratory site of the Forschungszentrum Karlsruhe, at 49 N, 8 E, 110 m above sea level. It consists of an extended (200 200m 2) array of electron detectors and muon detectors as well as of a compact and complex central detector system. The latter contains a dense scintillator matrix, muon tracking detectors, a s...

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 ...

RECENT RESULTS FROM THE CASA-MIA EXPERIMENT The Utah-Michigan-Chicago Collaboration

Results from the CASA-MIA cosmic ray experiment are presented. I discuss the apparatus and its performance, including new results on the identification of the shadows of the sun and moon used to determine the angular resolution. Limits on the emission of 100 TeV v-rays from the Crab Nebula are well below extrapolations from TeV observations. A search for diffuse "),-rays from the Galactic plane...
