Available in PDF, EPUB and Kindle. Book excerpt: This book offers a concise presentation of theoretical concepts characterizing and quantifying the slowing down of swift heavy ions in matter. Although the penetration of charged particles through matter has been studied for almost a hundred years, the quantitative theory for swift penetrating ions heavier than helium has been developed mainly during the past decade and is still progressing rapidly. The book addresses scientists and engineers working at accelerators with an interest in materials analysis and modification, medical diagnostics and therapy, mass spectrometry and radiation damage, as well as atomic and nuclear physicists. Although not a textbook, this monograph represents a unique source of state-of-the-art information that is useful to a university teacher in any course involving the interaction of charged particles with matter.

Download or read book Radioactive Ion Implantation of Thermoplastic Elastomers written by Veronica Borcea and published by Presses univ. de Louvain. This book was released on 2008 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The radioactive ion implantation wear measuring method (RII) has been used for many years as a tool to make highly sensitive real-time in-situ measurements of wear and corrosion in metallic or ceramic materials. The method consists of the controlled implantation of radioactive ions of limited decay time in a thin layer at the surface of the material. The progressive abrasion of the material results in a decline in radioactivity which is followed to monitor material losses. The application of RII to control the wear of polymers is potentially of interest, but it has been lagging behind because of uncertainties related to possible changes in material properties during and after the implantation, and to the exact shape of implantation profiles. In this thesis, we investigate these issues on two thermoplastic elastomers, among which one contains radiation-sensitive unsaturated bonds, using as ions 7Be, 7Li and Kr. The results of the sample characterisation indicate that the 7Be and 7Li implantations, under properly-selected conditions, do not induce significant modifications in the materials. The implantation of a stack of polymer thin films and the activity measurements performed to determine the implantation profile are also presented. The experimental results on the ion implantation profiles and the determination of calibration curves are presented and discussed in comparison with simulated results. The results indicate that it is possible to predict the implantation profile by means of simulations. This bodes well for the application of the RII method to polymer materials. An experimental study is presented regarding the possible redistribution of the implanted 7Be after implantation. Since very few existing experimental techniques are able to detect light elements implanted in polymer targets at fluences less or equal to 1012 cm-2, with implantation depths of a few μm, a new method is presented, which implies the use of plasma etching techniques in order to remove layers of polymers and measuring the remaining activity after each step. Our results indicate that a redistribution of the implanted ions takes place during the implantation process, resulting in a scrambling of the initial implantation profile. Nevertheless, provided a suitable methodology be used, wear measurements in polymers by using the RII method are still possible, as we propose in the thesis.

This book was released on 2018-10-13 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of protons and neutrons, or "nucleons"â€"the building blocks of atomic nucleiâ€"has advanced dramatically, both theoretically and experimentally, in the past half century. A central goal of modern nuclear physics is to understand the structure of the proton and neutron directly from the dynamics of their quarks and gluons governed by the theory of their interactions, quantum chromodynamics (QCD), and how nuclear interactions between protons and neutrons emerge from these dynamics. With deeper understanding of the quark-gluon structure of matter, scientists are poised to reach a deeper picture of these building blocks, and atomic nuclei themselves, as collective many-body systems with new emergent behavior. The development of a U.S. domestic electron-ion collider (EIC) facility has the potential to answer questions that are central to completing an understanding of atoms and integral to the agenda of nuclear physics today. This study assesses the merits and significance of the science that could be addressed by an EIC, and its importance to nuclear physics in particular and to the physical sciences in general. It evaluates the significance of the science that would be enabled by the construction of an EIC, its benefits to U.S. leadership in nuclear physics, and the benefits to other fields of science of a U.S.-based EIC.

Download or read book Nuclear Methods in Semiconductor Physics written by G. Langouche and published by Elsevier. This book was released on 1992-04-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two areas of experimental research explored in this volume are: the Hyperfine Interaction Methods, focusing on the microscopic configuration surrounding radioactive probe atoms in semiconductors, and Ion Beam Techniques using scattering, energy loss and channeling properties of highly energetic ions penetrating in semiconductors. A large area of interesting local defect studies is discussed. Less commonly used methods in the semiconductor field, such as nuclear magnetic resonance, electron nuclear double resonance, muon spin resonance and positron annihilation, are also reviewed. The broad scope of the contributions clearly demonstrates the growing interest in the use of sometimes fairly unconventional nuclear methods in the field of semiconductor physics.

Download or read book The Modelling of Radiation Damage in Metals Using Ehrenfest Dynamics written by Christopher Race and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomistic simulations of metals under irradiation are indispensable for understanding damage processes at time- and length-scales beyond the reach of experiment. Previously, such simulations have largely ignored the effect of electronic excitations on the atomic dynamics, even though energy exchange between atoms and electrons can have significant effects on the extent and nature of radiation damage. This thesis presents the results of time-dependent tight-binding simulations of radiation damage, in which the evolution of a coupled system of energetic classical ions and quantum mechanical electrons is correctly described. The effects of electronic excitations in collision cascades and ion channeling are explored and a new model is presented, which makes possible the accurate reproduction of non-adiabatic electronic forces in large-scale classical molecular dynamics simulations of metals.

Available in PDF, EPUB and Kindle. Book excerpt: For 75 years the stopping of energetic ions in matter has been a subject of great theoretical and experimental interest. The theoretical treatment of the stopping of ions in matter is largely due to the work of Bohr, 1-3 Bethe,4-6 Bloch,7. s and Lindhard,9-12 and it has been reviewed by Bohr,3 Fano,13 17 20 Jackson,14 Sigmund,15 Ahlen,16 and Ziegler et al. - Soon after the discovery of energetic particle emission from radioactive materials, there was interest in how these corpuscles were slowed down in traversing matter. In 1900, Marie Curie stated 21 the hypothesis that Hies rayons alpha sont des projectiles materiels susceptibles de perdre de leur vitesse en travers ant la matiere." Early attempts to evaluate this were incon clusive for there was not yet an accurate proposed model of the atom. Enough experimental evidence was collected in the next decade to make stopping power theory one of the central concerns of those attempting to develop an atomic model. J.J. Thomson, director of the prestigious Cavendish Laboratory, and Niels Bohr, a fresh postdoctoral scientist at Rutherford's Manchester Laboratory, both published almost simultaneously22. 23 an analysis of the stopping of charged particles by matter, and each contained many of their divergent ideas on the model of an atom. Thomson ignored in his paper the Rutherford alpha-particle scattering 24 experiment of a year before. But the nuclear atom with a heavy positively 25 charged core was the basis of Bohr's ideas.
