IMFREM - a computer program for analyses of intermediate mass-fragment emission in heavy ion reactions
Distortions of Experimental Muon Arrival Time Distributions of Extensive Air Showers by the Observation Conditions
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 is discussed, and different correction procedures, which involve
detailed simulations, are proposed and illustrated. The discussed distortions
are relevant for relatively small observation distances (R < 200 m) from the
EAS core. Their significance decreases with increasing observation distance and
increasing primary energies. Local arrival time distributions which refer to
the observed arrival time of the first local muon prove to be less sensitive to
the mass of the primary. This feature points to the necessity of arrival time
measurements with additional information on the curvature of the EAS disk.Comment: 10 pages, 6 figures, accepted for publication in Astroparticle

Charakteristika und Abhängigkeiten von Ankunftszeit- und Einfallswinkelverteilungen von Myonen ausgedehnter Luftschauer
Verschiedene charakteristische Eigenschaften und Korrelationen von Ankunftszeit- und Einfallswinkelverteilungen von Myonen ausgedehnter Luftschauer (EAS) werden untersucht auf der Grundlage von Monte-Carlo Simulationen der EAS Entwicklung mit Hilfe des Simulations-Codes CORSIKA. Die Ankunftszeitverteilungen und Winkel-verteilungen werden charakterisiert durch die Ankunftszeit bzw. Einfallswinkel des ersten Myons, durch Mittelwerte und Median-Werte der Verteilungen in den einzelnen Schauern.
Spezielles Augenmerk wird gerichtet auf Vielfach-Korrelationen bei gleichzeitigen Beobachtungen in verschiedenen Abständen vom Schauer-Zentrum. Es wird gezeigt, daß ein solcher Beobachtungsmode zusätzliche Informationen zur Verbesserung der Unterscheidung der Art der Primärteilchen liefert
Radio Propagation Environment Analysis for Neutrino Radio Detection in Salt Mines
Abstract a We consider a neutrino large-scale radio Cherenkov observatory in a Romanian salt mine. We include propagation effects on the radio signal generated and make a threshold analysis, taking into account how the pulse couples to a realistic receiver and signal-to-noise ratio limiting situations
