Book excerpt: A description is presented of a 2 Mev pulsed electron facility which employs a scanning electron beam probe at the target plane for the investigation of transient trapping phenomena in irradiated materials. The application of the facility to the study of trapped charge behavior in electron irradiated dielectrics is described somewhat below the threshold for spontaneous breakdown in the materials in a selected dose rate regime. A tentative interpretation is made of the characteristic decay curves for these high resistivity materials. An outline is presented of beam diagnostic techniques suitable for the 10 to the 10th power to 10 to the 11th power w/sq cm peak power electron beams available from a 4 Mv, 20 nanosecond pulsed electron accelerator and examples of their application discussed. A preliminary evaluation is made of some of the effects produced in materials by these relativistic self-focused streams at dose rates to 10 to the 15th power rad/sec. (Author).

Download or read book Radiation Effects in Materials written by Waldemar Alfredo Monteiro and published by BoD – Books on Demand. This book was released on 2016-07-20 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of radiation effects has developed as a major field of materials science from the beginning, approximately 70 years ago. Its rapid development has been driven by two strong influences. The properties of the crystal defects and the materials containing them may then be studied. The types of radiation that can alter structural materials consist of neutrons, ions, electrons, gamma rays or other electromagnetic waves with different wavelengths. All of these forms of radiation have the capability to displace atoms/molecules from their lattice sites, which is the fundamental process that drives the changes in all materials. The effect of irradiation on materials is fixed in the initial event in which an energetic projectile strikes a target. The book is distributed in four sections: Ionic Materials; Biomaterials; Polymeric Materials and Metallic Materials.

Download or read book Laser and Electron Beam Processing of Materials written by C.W. White and published by Elsevier. This book was released on 2012-12-02 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser and Electron Beam Processing of Materials contains the papers presented at the symposium on "Laser and Electron Beam Processing of Materials," held in Cambridge, Massachusetts, in November 1979, sponsored by the Materials Research Society. The compilation presents reports and research papers on the use of directed energy sources, such as lasers and electron beams for materials processing. The majority of the materials presented emphasize results on semiconductor materials research. Substantial findings on research on metals, alloys, and other materials are presented as well. Topics covered by the papers include the use of scanned cw sources (both photons and electrons) to recrystallize amorphous layers, enhanced substitutional solubility, solute trapping, zone refining of impurities, and constitutional supercooling. The use of lasers and electron beams to anneal ion implant damage and contacts formation, processing of ion-implanted metals, and surface alloying of films deposited on metallic surfaces are also discussed. Metallurgists, engineers, and materials scientists will find the book very insightful.

Download or read book Cryotechniques in Biological Electron Microscopy written by Rudolf A. Steinbrecht and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: To preserve tissue by freezing is an ancient concept going back pre sumably to the practice of ice-age hunters. At first glance, it seems as simple as it is attractive: the dynamics of life are frozen in, nothing is added and nothing withdrawn except thermal energy. Thus, the result should be more life-like than after poisoning, tan ning and drying a living cell as we may rudely call the conventional preparation of specimens for electron microscopy. Countless mishaps, however, have taught electron microscopists that cryotechniques too are neither simple nor necessarily more life-like in their outcome. Not too long ago, experts in cryotechniques strictly denied that a cell could truly be vitrified, i.e. that all the solutes and macro molecules could be fixed within non-crystalline, glass-like solid water without the dramatic shifts and segregation effects caused by crystallization. We now know that vitrification is indeed pos sible. Growing insight into the fundamentals of the physics of water and ice, as well as increasing experience of how to cool cells rapidly enough have enlivened the interest in cryofixation and pro duced a wealth of successful applications.

Download or read book Electron Beam Analysis of Materials written by M. H. Loretto and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of materials using electron beam techniques has developed continuously for over twenty years and there are now many different methods of extracting detailed structural and chemical information using electron beams. These techniques which include electron probe microanalysis, trans mission electron microscopy, Auger spectroscopy and scanning electron microscopy have, until recently, developed more or less independently of each other. Thus dedicated instruments designed to optimize the performance for a specific application have been available and correspondingly most of the available textbooks tend to have covered the theory and practice of an individual technique. There appears to be no doubt that dedicated instru ments taken together with the specialized textbooks will continue to be the appropriate approach for some problems. Nevertheless the underlying electron-specimen interactions are common to many techniques and in view of the fact that a range of hybrid instruments is now available it seems appropriate to provide a broad-based text for users of these electron beam facilities. The aim of the present book is therefore to provide, in a reasonably concise form, the material which will allow the practitioner of one or more of the individual techniques to appreciate and to make use of the type of information which can be obtained using other electron beam techniques.

Download or read book Characterisation of Radiation Damage by Transmission Electron Microscopy written by M.L Jenkins and published by CRC Press. This book was released on 2000-11-21 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of Radiation Damage by Transmission Electron Microscopy details the electron microscopy methods used to investigate complex and fine-scale microstructures, such as those produced by fast-particle irradiation of metals or ion implantation of semiconductors. The book focuses on the methods used to characterize small point-defect clusters, such as dislocation loops, because the coverage in general microscopy textbooks is limited and omits many of the problems associated with the analysis of these defects. The book also describes in situ, high-resolution, and analytical techniques. Techniques are illustrated with examples, providing a solid overview of the contribution of TEM to radiation damage mechanisms. The book is most useful to researchers in, or entering into, the field of defect analysis in materials.
