Book Synopsis Emission of Radio Waves in Particle Showers by : Anne Zilles
Download or read book Emission of Radio Waves in Particle Showers written by Anne Zilles and published by Springer. This book was released on 2017-08-08 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers the first laboratory validation of microscopic simulations of radio emission from particle showers, including a detailed description of the simulation study. It presents a potential future avenue for resolving the mass composition of cosmic rays via radio detection of air showers. Particle showers are created from cascading interactions when high-energy particles collide with matter, e.g. with air in the case of cosmic radiation, or with a particle detector in the case of experiments at CERN. These showers can consist of billions of particles, mostly electrons, positrons and photons. They emit radio waves when the absorbing medium is in a magnetic field, and this radio emission can be used as a novel means of detecting and drawing inferences on the shower and the primary particle. The new method is currently being established in cosmic ray research, where large antenna arrays may soon replace or complement traditional particle detectors. In thi s study, a complete microscopic simulation of a radio-emission experiment conducted at Stanford Linear Accelerator Center (SLAC), Stanford/USA, is performed, and the underlying physical models are validated. The model is subsequently applied to the Square Kilometre Array (SKA) project, which is a large interferometer for radio astronomy. It is demonstrated that the SKA, with some modifications, might also be used for cosmic ray research based on radio detection of high-energy particles from the cosmos.
Book Synopsis Near-field Effects in Radio Frequency Emission from Particle Showers in a Dense Medium by : Rachel J. Hyneman
Download or read book Near-field Effects in Radio Frequency Emission from Particle Showers in a Dense Medium written by Rachel J. Hyneman and published by . This book was released on 2015 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SLAC T-510 Experiment studied the effects of a magnetic field upon the radio- frequency emission from particle showers in high-density polyethylene. Ultra-High Energy (UHF) and Very High Frequency (VHF) antennas were used to measure the radio frequency (RF) radiation from particle showers in the target. Special near field data runs were performed with the UHF antenna array positioned closer to the target (along the beam axis). The signal was split into two linearly polarized components, vertical and horizontal, arising from two different mechanisms: the Askaryan and Magnetic effects, respectively. Peak voltage data from the near-field runs was used to determine the behavior of the radiation amplitude as a function of distance from the target and angle made with respect to the beam line. Power spectral densities were produced using near field runs to analyze how various frequency ranges behaved as a function of distance. Initial results indicate that the amplitude dependence of the peak voltage on angle remains consistent even as the antennas are moved further from the target. A 1/R correction describes the effects of moving away from the target well. Spectral analysis reveals unclear effects in the lower frequency ranges. Although near field interference might be expected, such variations are likely dominated by reflections of RF emission within the target.
Book Synopsis Characterizing Radio Emission from Extensive Air Showers with the SLAC-T510 Experiment, with Applications to ANITA by : Katharine B. Mulrey
Download or read book Characterizing Radio Emission from Extensive Air Showers with the SLAC-T510 Experiment, with Applications to ANITA written by Katharine B. Mulrey and published by . This book was released on 2018 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrino and cosmic ray astronomy allow scientists to gather information about the highest energy processes in the universe. However, since cosmic rays are charged nuclei moving in astrophysical magnetic fields, it has not been possible to determine their sources by studying their arrival directions. A pointed neutrino flux is expected at such energies, either direct from the sources or due to the GZK process, where high energy cosmic rays interact with cosmic microwave photons as they travel through the universe. Detection methods make use of particle cascades initiated by these high energy primaries. In particular, the electromagnetic radiation in radio frequencies generated by particle cascades is a powerful tool. Particle cascades emit radiation by the Askaryan process, where a charge excess in the cascade emits coherently. In the presence of a magnetic field, a transverse current develops which also emits coherently in the radio regime. Theoretical models describe this radiation and are widely used to reconstruct the energy, geometry, and composition of observed events. Therefore, understanding and validating models describing this radiation is of great importance to neutrino and cosmic ray astronomy. ☐ The SLAC T-510 beam test is the first experiment to produce a particle cascade in a controlled setting in the presence of a magnetic field. Radio-frequency (RF) emission is collected in the region of the Cherenkov cone in two polarizations designed to separately capture Askaryan and magnetically induced radiation. Field intensity, linearity with magnetic field, and spectral content are compared to particle-level simulations. The data provide experimental evidence supporting theoretical models, and show the first laboratory results of the scaling of the radiative strength with the magnetic field. ☐ SLAC T-510 grew out of a need to calibrate the sensitivity of the ANITA (Antarctic Impulsive Transient Antenna) experiment to cosmic ray air showers. ANITA uses radio techniques to detect the highest energy neutrinos and cosmic rays. An array of broadband antennas flies over Antarctica looking for signals from neutrinos interacting in ice and cosmic rays interacting in the atmosphere. The ANITA 3 flight took place in the austral summer of 2014-2015. ☐ In this dissertation I describe the SLAC T-510 experiment and results, as well as preparation and flight from the 2014 ANITA 3 campaign.

Book Synopsis Instruments and Methods for the Radio Detection of High Energy Cosmic Rays by : Frank Schröder
Download or read book Instruments and Methods for the Radio Detection of High Energy Cosmic Rays written by Frank Schröder and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmic rays consist of elementary particles with enormous energy which originate from outside our solar system and constantly hit the Earth’s atmosphere. Where do these cosmic rays originate? How does nature accelerate the cosmic-ray particles to energies with orders of magnitude beyond the limits of manmade particle accelerators? What can we learn by measuring the interactions of the cosmic rays with the atmosphere? Digital radio-antenna arrays offer a promising, complementary measurement method for high-energy cosmic rays. This thesis reports on substantial advances in the development of the radio technique, which will be used to address these questions in future experiments.

Book Synopsis Large Area Networked Detectors For Particle Astrophysics by : Pierre Sokolsky
Download or read book Large Area Networked Detectors For Particle Astrophysics written by Pierre Sokolsky and published by World Scientific. This book was released on 2022-09-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The universe is pervaded by particles with extreme energies, millions of times greater than we can produce on Earth. They have been a mystery for over a century. Now, current and future experiments in particle astrophysics are leading us to answers to the most fundamental questions about them. How does nature accelerate the highest energy particles in the universe? Do new interactions between them occur at such extreme energies? Are there unknown aspects of spacetime that can be uncovered by studying these particles?This book brings together three fields within 'extreme astronomy': ultra-high-energy cosmic ray physics, neutrino astronomy, and gamma-ray astronomy, and discusses how each can help answer these questions. Each field is presented with a theoretical introduction that clearly elucidates the key questions scientists face. This is followed by chapters that discuss the current set of experiments — how they work and their discoveries. Finally, new techniques and approaches are discussed to solve the mysteries uncovered by the current experiments.

Book Synopsis Cosmic Rays at Earth by : P.K.F. Grieder
Download or read book Cosmic Rays at Earth written by P.K.F. Grieder and published by Elsevier. This book was released on 2001-07-27 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery.Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches.
