Proposal of NEVOD-EAS shower array

Callibration of a homemade 4-fold Water Cherenkov Detector array, by detection of EAS events

Milagrito, a TeV air-shower array

Milagrito, a large, covered water-Cherenkov detector, was the world's "rst air-shower-particle detector sensitive to cosmic gamma rays below 1 TeV. It served as a prototype for the Milagro detector and operated from February 1997 to May 1998. This paper gives a description of Milagrito, a summary of the operating experience, and early results that demonstrate the capabilities of this technique....

The Stockholm Educational Air Shower Array

The primary goal of the Stockholm Educational Air Shower Array (‘SEASA’) project is to bring the intellectual and technical challenge of scientific research to high-school (16 – 18 years old) students. The focus of the project is the high energy cosmic radiation which continually bombards the earth’s atmosphere, generating showers of secondary particles. These showers can be detected by a netwo...

Time Calibration of the Radio Air Shower Array LOPES

LOPES is a digitally read out antenna array consisting of 30 calibrated dipole antennas. It is located at the site of the KASCADE-Grande experiment at Forschungszentrum Karlsruhe and measures the radio emission of cosmic ray air showers in the frequency band from 40 to 80 MHz. LOPES is triggered by KASCADE and uses the KASCADE reconstruction of the shower axis as an input for the analysis of th...

A Giant Air Shower Array in Nord Rhein Westfalen

The energy spectrum of cosmic rays appears to extend unattenuated beyond 5 · 10 eV although photoproduction of pions by collisions of the primary protons with the universal 2.7◦ K microwave background should have cut off the cosmic ray energy spectrum. The assumption that the highest energy particles of cosmic rays are protons is a most natural one and is also in accord with the observed featur...
