【 摘 要 】

KASCADE-Grande is an air shower observatory devoted to the detection of cosmic rays in the 1016- 1018eV energy range. For each event the arrival direction, the total number of charged particles (Nch) and the total number of muons (Nμ), at detection level (i.e. 110 m a.s.l.), are measured. The detection of these observarbles, with high accuracy, allows the study of the primary spectrum, chemical composition and large scale anisotropies, that are the relevant informations to investigate the astrophysics of cosmic rays in this energy range. These studies are of main importance to deeply investigate the change of slope of the primary spectrum detected at ∼ 4 × 1015eV, also known as the knee, and to search for the transition from galactic to extra-galactic cosmic rays.
