Available in PDF, EPUB and Kindle. Book excerpt: Short Historical Overview In the 1940s, two phenomena in the ?eld of cosmic rays (CR) forced scientists to think that the Sun is a powerful source of high-energy particles. One of these was discovered because of the daily solar variation of CR, which the maximum number of CR observed near noon (referring to the existence of continuous ?ux of CR from the direction of the Sun); this became the experimental basis of the theory that CR’s ́ originate from the Sun (or, for that matter, from within the solar system) (Alfven 1954). The second phenomenon was discovered when large ?uxes of high energy particles were detected from several solar ?ares, or solar CR. These are the - called ground level events (GLE), and were ?rst observed by ionization chambers shielded by 10 cm Pb (and detected mainly from the secondary muon-component CR that they caused) during the events of the 28th of February 1942, the 7th of March 1942, the 25th of July 1946, and the 19th of November 1949. The biggest such event was detected on the 23rd of February 1956 (see the detailed description in Chapters X and XI of Dorman, M1957). The ?rst phenomenon was investigated in detail in Dorman (M1957), by ?rst correcting experimental data on muon temperature effects and then by using coupling functions to determine the change in particle energy caused by the solar-diurnal CR variation.
Download or read book Status of the Dosimetry for the Radiation Effects Research Foundation DS86 written by National Research Council and published by National Academies Press. This book was released on 2001-10-04 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Committee on Dosimetry for the Radiation Effects Research Foundation (RERF) was set up more than a decade ago at the request of the U.S. Department of Energy. It was charged with monitoring work and experimental results related to the Dosimetry System 1986 (DS86) used by RERF to reconstruct the radiation doses to the survivors in Hiroshima and Nagasaki. At the time it was established, DS86 was believed to be the best available dosimetric system for RERF, but questions have persisted about some features, especially the estimates of neutrons resulting from the Hiroshima bomb. This book describes the current situation, the gamma-ray dosimetry, and such dosimetry issues as thermal-neutron discrepancies between measurement and calculation at various distances in Hiroshima and Nagasaki. It recommends approaches to bring those issues to closure and sets the stage for the recently convened U.S. and Japan Working Groups that will develop a new dosimetry for RERF. The book outlines the changes relating to DS86 in the past 15 years, such as improved numbers that go into, and are part of, more sophisticated calculations for determining the radiations from bombs that reach certain distances in air, and encourages incorporation of the changes into a revised dosimetry system.

Download or read book Radiation Effects and Soft Errors in Integrated Circuits and Electronic Devices written by Dan M. Fleetwood and published by World Scientific. This book was released on 2004 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed treatment of radiation effects in electronic devices, including effects at the material, device, and circuit levels. The emphasis is on transient effects caused by single ionizing particles (single-event effects and soft errors) and effects produced by the cumulative energy deposited by the radiation (total ionizing dose effects). Bipolar (Si and SiGe), metalOCooxideOCosemiconductor (MOS), and compound semiconductor technologies are discussed. In addition to considering the specific issues associated with high-performance devices and technologies, the book includes the background material necessary for understanding radiation effects at a more general level. Contents: Single Event Effects in Avionics and on the Ground (E Normand); Soft Errors in Commercial Integrated Circuits (R C Baumann); System Level Single Event Upset Mitigation Strategies (W F Heidergott); Space Radiation Effects in Optocouplers (R A Reed et al.); The Effects of Space Radiation Exposure on Power MOSFETs: A Review (K Shenai et al.); Total Dose Effects in Linear Bipolar Integrated Circuits (H J Barnaby); Hardness Assurance for Commercial Microelectronics (R L Pease); Switching Oxide Traps (T R Oldham); Online and Realtime Dosimetry Using Optically Stimulated Luminescence (L Dusseau & J Gasiot); and other articles. Readership: Practitioners, researchers, managers and graduate students in electrical and electronic engineering, semiconductor science and technology, and microelectronics."
Download or read book Solar Particle Radiation Storms Forecasting and Analysis written by Olga E Malandraki and published by . This book was released on 2020-10-08 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar energetic particles (SEPs) emitted from the Sun are a major space weather hazard motivating the development of predictive capabilities. This book presents the results and findings of the HESPERIA (High Energy Solar Particle Events forecasting and Analysis) project of the EU HORIZON 2020 programme. It discusses the forecasting operational tools developed within the project, and presents progress to SEP research contributed by HESPERIA both from the observational as well as the SEP modelling perspective. Using multi-frequency observational data and simulations HESPERIA investigated the chain of processes from particle acceleration in the corona, particle transport in the magnetically complex corona and interplanetary space, to the detection near 1 AU. The book also elaborates on the unique software that has been constructed for inverting observations of relativistic SEPs to physical parameters that can be compared with space-borne measurements at lower energies. Introductory and pedagogical material included in the book make it accessible to students at graduate level and will be useful as background material for Space Physics and Space Weather courses with emphasis on Solar Energetic Particle Event Forecasting and Analysis.
