Available in PDF, EPUB and Kindle. Book excerpt: Written primarily for researchers and graduate students who are new in this emerging field, this book develops the necessary tools so that readers can follow the latest advances in this subject. Readers are first guided to examine the basic informations on nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A good survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarised.

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 Electronic Energy Loss of Heavy Ions and Its Effects in Ceramics written by Ke Jin and published by . This book was released on 2015 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy loss of medium energy heavy ions (i.e. Cl, Br, I, and Au) in thin compound foils containing light elements (i.e. silicon carbide and silicon dioxide) is directly measured using a time-of-flight elastic recoil detection analysis (ToF-ERDA) technique. An improved data analysis procedure is proposed to provide the experimentally determined electronic stopping powers. This analysis procedure requires reliable predictions of nuclear stopping. Thus, the nuclear stopping predicted by the Stopping and Range of Ions in Matter (SRIM) code is validated by measuring the angular distribution of 1 MeV Au ions after penetrating a thin silicon nitride foil, using a secondary ion mass spectrometry (SIMS). In order to validate our derived electronic stopping power values, Rutherford backscattering spectrometry (RBS) and SIMS are utilized as complementary techniques to measure the depth profiles of implanted Au ions in SiC. Moreover, the original version of the SRIM code, TRIM-85, is modified to adopt our derived electronic stopping powers to predict ion distributions. The comparison studies show that the ion distributions predicted based on our derived electronic stopping powers agree well with the experimental results, but exhibit considerable discrepancies with the SRIM predictions. The large deviation from SRIM predictions is further observed in other materials. The distributions of implanted Au ions with various energies from 1 to 15 MeV are measured in Si and MgO. The electronic stopping powers for Au ions in Si are estimated based on the measured ion profiles. For Au ion irradiation in MgO, significant channeling effects on the ion and damage profiles are observed for the irradiations along both axial and planar channels. Furthermore, the effect of electronic energy deposition from medium energy heavy ions (i.e. 21 MeV Ni) on the damage evolution in MgO, in which the initial defects are induced using 1 MeV Au, is studied. The evolution in damage level and damage structure under the irradiations is characterized using RBS/ion channeling technique combined with transmission electron microscopy (TEM).

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.

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.

Download or read book Proton Therapy Physics written by Harald Paganetti and published by CRC Press. This book was released on 2016-04-19 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proton Therapy Physics goes beyond current books on proton therapy to provide an in-depth overview of the physics aspects of this radiation therapy modality, eliminating the need to dig through information scattered in the medical physics literature. After tracing the history of proton therapy, the book summarizes the atomic and nuclear physics background necessary for understanding proton interactions with tissue. It describes the physics of proton accelerators, the parameters of clinical proton beams, and the mechanisms to generate a conformal dose distribution in a patient. The text then covers detector systems and measuring techniques for reference dosimetry, outlines basic quality assurance and commissioning guidelines, and gives examples of Monte Carlo simulations in proton therapy. The book moves on to discussions of treatment planning for single- and multiple-field uniform doses, dose calculation concepts and algorithms, and precision and uncertainties for nonmoving and moving targets. It also examines computerized treatment plan optimization, methods for in vivo dose or beam range verification, the safety of patients and operating personnel, and the biological implications of using protons from a physics perspective. The final chapter illustrates the use of risk models for common tissue complications in treatment optimization. Along with exploring quality assurance issues and biological considerations, this practical guide collects the latest clinical studies on the use of protons in treatment planning and radiation monitoring. Suitable for both newcomers in medical physics and more seasoned specialists in radiation oncology, the book helps readers understand the uncertainties and limitations of precisely shaped dose distribution.
