Available in PDF, EPUB and Kindle. Book excerpt: Extensive air showers are a very unique phenomenon. In the more than six decades since their discovery by Auger and collaborators we have learned a lot about these extremely energetic events and gained deep insight into high-energy phenomena, particle physics and astrophysics. In this Tutorial, Reference Manual and Data Book Peter K. F. Grieder provides the reader with a comprehensive view of the phenomenology and facts of the various types of interactions and cascades, theoretical background, experimental methods, data evaluation and interpretation and air shower simulation. He discusses astrophysical aspects of the primary radiation and addresses remaining puzzling questions that cannot yet be answered. They remain as a challenge for present and future research in the field. The book is split into two volumes. Volume I deals mainly with the basic theoretical framework of the processes that determine an air shower and ends with a summary of ways and means to extract information from air shower observations on the primary radiation. It also presents a compilation of data of our current knowledge of the high energy portion of the primary spectrum and composition. Volume II contains mainly compilations of data of experimental and theoretical nature as well as predictions from simulations of individual air shower constituents. Also included are chapters dedicated exclusively to special processes and detection methods. Extensive up-to-date reference lists appear at the end of each chapter.

Download or read book Extensive Air Showers written by M. V. S. Rao and published by World Scientific. This book was released on 1998 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrahigh energy cosmic rays carry information about their sources and the intervening medium apart from providing a beam of particles for studying certain features of high energy interactions currently inaccessible at man-made accelerators. They can at present be studied only via the extensive air showers (EAS's) they generate while passing through the Earth's atmosphere, since their fluxes are too low for the experiments of limited capability flown in balloons and satellites. The EAS is generated by a series of interactions of the primary cosmic ray and its progeny with the atmospheric nuclei. The exponential nature of the atmosphere spreads the air showers laterally over several hundreds of meters, thus enabling ground-based arrays of relatively inexpensive detectors to record and study them.This book describes the EAS phenomenology, the detectors and techniques used, and the latest results on the energy spectrum and composition of the primaries of EAS's and the results on high energy interactions obtained from EAS studies. It also describes the new TeV and PeV gamma ray astronomy (which has been developing over the past decade) and the newly emerging neutrino astronomy, which are related to the origin of cosmic rays.This book serves as an introduction as well as a reference for researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Cosmic ray physics has recently attracted a great deal of attention from the high energy physics community because of the discovery of new sources and the advent of new techniques. The result of a series of lectures prepared for graduate students and postdoctoral researchers, this book is a general introduction to experimental techniques and results in the field of ultrahigh energy cosmic rays. It succinctly summarizes the rapidly developing field, and provides modern results that include data from newer detectors. Combining experiment and theory, the text explores the results of a single, easy-to-understand experiment to tie together various issues involved in the physics of ultrahigh energy cosmic rays.

This book was released on 2015 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra-high-energy cosmic rays (UHECR) are particles of uncertain origin and composition, with energies above 1 EeV (1018 eV or 0.16 J). The measured flux of UHECR is a steeply decreasing function of energy. The largest and most sensitive apparatus built to date to record and study cosmic ray Extensive Air Showers (EAS) is the Pierre Auger Observatory. The Pierre Auger Observatory has produced the largest and finest amount of data ever collected for UHECR. A broad physics program is being carried out covering all relevant topics of the field. Among them, one of the most interesting is the problem related to the estimation of the mass composition of cosmic rays in this energy range. Currently the best measurements of mass are those obtained by studying the longitudinal development of the electromagnetic part of the EAS with the Fluorescence Detector. However, the collected statistics is small, specially at energies above several tens of EeV. Although less precise, the volume of data gathered with the Surface Detector is nearly a factor ten larger than the fluorescence data. So new ways to study composition with data collected at the ground are under investigation. The subject of this thesis follows one of those new lines of research. Using preferentially the time information associated with the muons that reach the ground, we try to build observables related to the composition of the primaries that initiated the EAS. A simple phenomenological model relates the arrival times with the depths in the atmosphere where muons are produced. The experimental confirmation that the distributions of muon production depths (MPD) correlate with the mass of the primary particle has opened the way to a variety of studies, of which this thesis is a continuation, with the aim of enlarging and improving its range of applicability. We revisit the phenomenological model which is at the root of the analysis and discuss a new way to improve some aspects of the model. We carry out a thorough revision of the original analysis with the aim of understanding the different contributions to the total bias and resolution when building MPDs on an event-by-event basis. We focus on an alternative way to build MPDs by considering average MPDs for ensembles of air-showers, with the aim of enlarging the range of applicability of this kind of analysis. Finally, we analyze how different improvements in the Surface Detector electronics and its internal configuration affect the resolution of the MPD. We conclude by summarizing the main results and discussing potential ways to improve MPD-based mass composition studies.

This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ALEPH detector at LEP has been supplemented with five scintillator stations to measure the muon component of cosmic ray showers underground. We report the measurements of coincidences over distances up to about 1 km which are sensitive to the forward production of hadronic interactions and the chemical composition of primary cosmic rays in the energy range around 1015 eV. The results are compared to the expectations obtained from Monte Carlo simulation. Our results indicate that the observed decoherence curve of muons is compatible with a light primary composition. In addition, the arrival times of muons underground as measured with scintillator stations allow to reconstruct the muon arrival directions in 3-fold coincidence events. These results are compared to shower simulations.

Available in PDF, EPUB and Kindle. Book excerpt: We describe the measurement of the depth of maximum, X{sub max}, of the longitudinal development of air showers induced by cosmic rays. Almost 4000 events above 1018 eV observed by the fluorescence detector of the Pierre Auger Observatory in coincidence with at least one surface detector station are selected for the analysis. The average shower maximum was found to evolve with energy at a rate of (10621{sup +35}) g/cm2/decade below 10{sup 18.24 ± 0.05}eV, and (24 {+-} 3) g/cm2/decade above this energy. The measured shower-to-shower fluctuations decrease from about 55 to 26 g/cm2. The interpretation of these results in terms of the cosmic ray mass composition is briefly discussed.
