This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An experiment designed to measure Cerenkov radiation from cosmic ray extensive air showers was deployed at Dugway, Utah from October 1977 to March 1980. This thesis is concerned with Cerenkov light measurements made at Dugway during the second season of observation from October 1978 to March 1979.An introduction to cosmic rays and extensive air showers is followed by a review of previous studies (both theoretical and experimental) of Cerenkov radiation from EAS. Particular attention is given to Cerenkov light parameters which relate to the depth of electron cascade maximum. A detailed account of the design and performance of the array of Cerenkov light detectors is then given, combined with an account of the first season of observation from October to December 1977.The calibration of the equipment during the second season of observation is discussed, indicating the sensitivity of the equipment to a light flux. This is followed by a description of the procedure employed to reduce the data from the experiment. A small sample of the recorded showers was selected to form the basis of a preliminary analysis presented in this thesis. Analysis of this sample of showers enabled the average characteristics of Cerenkov radiation from showers of energy 5x10( 16) - 5x10( 17)eV to be determined. The study of the average characteristics of Cerenkov radiation indicated that the lateral distribution of photon density, the peak height and FWHM of the Cerenkov pulses were sensitive to the zenith angle and energy of the showers. From the lateral distribution of photon density a primary energy estimator was established. Consistency was found between the preliminary results presented here and computer simulations. There were also favourable comparisons between the results of the Dugway experiment and similar measurements made at other establishments. A survey of vertically incident computer simulations of extensive air showers indicated that the basic assumptions behind the recently introduced elongation theorem may not be valid. Finally, a review of the future work of the Dugway experiment is presented.

Available in PDF, EPUB and Kindle. Book excerpt: The Cerenkov light associated with EAS of sizes between aprox. 2 times 10 to the 4th and 2 times 10 to the 6th power was observed. The size spectrum of the associated showers is much flatter than that of all events, and the maximum pulse heights recorded for showers of a given size are almost independent of the particle number. This can be interpreted as a consequence of the zenith angle distribution of the EAS. The maximum intensity of the Cerenkov light was found not at the centre but at some 20 m from it. This may be explained by the angular divergence of the shower particles. (Author).

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.

This book was released on 2012-01-08 with total page 1251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The handbook centers on detection techniques in the field of particle physics, medical imaging and related subjects. It is structured into three parts. The first one is dealing with basic ideas of particle detectors, followed by applications of these devices in high energy physics and other fields. In the last part the large field of medical imaging using similar detection techniques is described. The different chapters of the book are written by world experts in their field. Clear instructions on the detection techniques and principles in terms of relevant operation parameters for scientists and graduate students are given.Detailed tables and diagrams will make this a very useful handbook for the application of these techniques in many different fields like physics, medicine, biology and other areas of natural science.

Available in PDF, EPUB and Kindle. Book excerpt: The `International Heidelberg Workshop on TeV Gamma-Ray Astrophysics' brought together astrophysicists from the various fields which play a role in the formation of high energy gamma-ray emission. In particular, theoretical and observational aspects of the physics and astrophysics of pulsars and quasars, the acceleration of particles at Supernova Remnants and other strong astrophysical shock fronts, and cascade processes in universal background photon fields were comprehensively discussed in more than thirty reviews by leading experts. In their entirety these reviews describe the birth of a new field of astronomy. This field concerns cosmic gamma-rays of very high energy which are observed with ground-based optical telescopes due to the Cherenkov emission of the secondary particles created by the interaction of these gamma-rays with atoms in the Earth's atmosphere. Beyond that, the workshop encompassed the latest developments and trends in theory and observation of cosmic gamma-ray sources of all energies, from nuclear gamma-ray lines in the MeV-region, through the Bremsstrahlung, Inverse Compton, and pion decay continuum emission, to gamma-rays due the decay of exotic relics from the early Universe. Audience: Specialists as well as students in physics and astrophysics and young research workers.
