30TH INTERNATIONAL COSMIC RAY CONFERENCE Separation of the electromagnetic and the muon component in EAS by their arrival times

چکیده
KASCADE-Grande is a ground based multi-detector experiment measuring extensive air showers in order to study the primary cosmic ray energy spectrum in the energy range from 10 eV to 10 eV. A Flash-ADC based data acquisition system in KASCADE-Grande allows to study the temporal structure of extensive air showers. Muons in extensive air showers are thought to arrive on average earlier than the particles of the electromagnetic shower component. The separation of electrons and muons according to their arrival times poses an alternative to the measurement of the shower muon content with muon detectors. Approximately one year of KASCADE-Grande data have been analyzed to study the arrival times of the electromagnetic and the muonic shower components.

The Muon Tracking Detector in the KASCADE-Grande experiment allows the measurement of muon directions up to 700 m from the shower center. It means, that nearly all muons produced in a shower and surviving to the ground level are subject of investigation. It is important not only for studying mean muon production heights but also for investigations of EAS muon pseudorapidity distributions. These...

The Pierre Auger Observatory allows the measurement of both longitudinal profiles and lateral particle distributions of high-energy showers. The former trace the overall shower development, mainly of the electromagnetic component close to the core where the latter reflect the particle densities in the tail of the shower far away from the core and are sensitive to both the muonic and electromagn...

KASCADE-Grande is a multi detector setup for the investigation of extensive air showers in the 10 − 10 eV energy range. With the Grande array it is possible to reconstruct the shower core position, the arrival direction and the total number of charged particles in the shower. The Grande array measures in coincidence with the original KASCADE muon array consisting of 622 m shielded scintillators...

A large area (128m) Muon Tracking Detector (MTD), located within the KASCADE experiment, has been built with the aim to identify muons (Eμ >0.8GeV) and their directions in extensive air showers by track measurements under more than 18 r.l. shielding. The orientation of the muon track with respect to the shower axis is expressed in terms of the radialand tangential angles. By means of triangulat...
