Abstract:
The KASCADE-Grande experiment, located at Forschungszentrum, Karlsruhe (Germany), is a multi-component extensive air-shower experiment to study cosmic rays and their interactions at primary energies 10(14)-10(18) eV. After detailed investigations of the knee in the spectrum with KASCADE and EAS-TOP experiments, the main goal of KASCADE-Grande is to provide conclusive results on the knee region by detecting the expected iron knee in the spectrum at around 10(17) eV, and measuring the composition in the possible transition region between galactic and extragalactic components. Due to its multi-component characteristics, basically the former KASCADE experiment enriched by two new arrays of scintillator detectors (Grande and Piccolo), with the aim of providing a large acceptance area (0.5 km(2)) and prompt trigger signal, KASCADE-Grande is a suitable array to provide refined measurements in the 10(16)-10(18) eV region. In the following, we briefly report on the characteristics of the detector, its performance, and first results based on 2 years of data taking. (C) 2008 Elsevier B.V. All rights reserved.
