The influence of the detector system on the measurements of muon arrival times in Extensive Air Showers (EAS)
نویسنده
چکیده
Arrival time distributions of EAS muons carry information about the production profile of the EAS muonic component. The measured distributions are affected and distorted by various interwoven effects which arise from the time resolution of the timing detectors, from fluctuations of the reference time and the number of detected muons spanning the arrival time distribution of a single EAS event. The origin of these effects is discussed and correction procedures which involve detailed simulations are proposed.

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 pa...

The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air showers (EAS), including measurements of the EAS particle content on ground which is sensitive to high-energy hadronic interactions. We present the results of several independent measurements of the EAS muon content ...

Event-by-event measured arrival time distributions of Extensive Air Shower (EAS) muons are affected and distorted by various interrelated effects which originate from the time resolution of the timing detectors, from fluctuations of the reference time and the number (multiplicity) of detected muons spanning the arrival time distribution of the individual EAS events. The origin of these effects ...

Nµ/Ne, muon to electron population ratio in extensive air showers at high altitudes has been shown to be a suitable estimator of primary cosmic rays mass composition. This study is based on simulated extensive air showers. The Nµ/Ne ratio has been obtained in 100 depths from the top of the atmosphere to the sea level for different primary particle masses and energies. An empirical relation bet...
