This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work details the advancement and understanding of fusion neutron generation capabilities using a deuterium fueled spherical gridded inertial electrostatic confinement (IEC) device operating up to 200 kV at the University of Wisconsin-Madison. The goal of this work was to extend the experimental and theoretical understanding of gridded IEC operations to previously unachieved 200 kV cathode operation and to investigate long term trends in the neutron production rate performance. To support this experimental investigation, hardware with the capability to reliably sustain 200 kV operation was successfully developed by constructing a resistively divided 2-stage high voltage vacuum feedthrough. Repeated measurements of the neutron production rate under fixed experimental conditions were performed over the span of 100 operational runs, which showed an upward trend in the neutron production rate performance. An investigation into the impact of impurity gas in the chamber during operation showed the reduction of impurity gas in the system and an increase in neutron production rate are correlated. An estimation of the neutron production rate increase over these runs due to embedded fusion reactions in the chamber wall showed a fuel density build up near the surface by the implantation of fast neutral deuterium particles leaving the system can plausibly account for the upward trend in neutron production rate measurements. Parametric studies measured the neutron production rate with variations in the device cathode voltage (10-200 kV), cathode current (30-100 mA) and chamber pressure (0.2-1.7 mTorr D2), and comparisons with a theoretical model are made. The results of this study showed the neutron production rate scales linearly with current as expected with a beam-target fusion regime and scales in a complex manner with voltage and pressure. Comparisons made to a theoretical model of the neutron production rate using an integral transport code showed the absolute neutron production rate prediction by the model is a factor of 7.8 lower than experimental measurements. A new record for steady-state D-D neutron production rate of 3.8x108 neutrons/s has been achieved in a gridded IEC device at a cathode voltage of 200 kV, cathode current of 100 mA, and chamber pressure of 1.0 mTorr D2.
Download or read book Inertial Electrostatic Confinement IEC Fusion written by George H. Miley and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.

Download or read book The Physics of Inertial Fusion written by Stefano Atzeni and published by OUP Oxford. This book was released on 2004-06-03 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is on inertial confinement fusion, an alternative way to produce electrical power from hydrogen fuel by using powerful lasers or particle beams. It involves the compression of tiny amounts (micrograms) of fuel to thousand times solid density and pressures otherwise existing only in the centre of stars. Thanks to advances in laser technology, it is now possible to produce such extreme states of matter in the laboratory. Recent developments have boosted laser intensities again with new possibilities for laser particle accelerators, laser nuclear physics, and fast ignition of fusion targets. This is a reference book for those working on beam plasma physics, be it in the context of fundamental research or applications to fusion energy or novel ultra-bright laser sources. The book combines quite different areas of physics: beam target interaction, dense plasmas, hydrodynamic implosion and instabilities, radiative energy transfer as well as fusion reactions. Particular attention is given to simple and useful modelling, including dimensional analysis and similarity solutions. Both authors have worked in this field for more than 20 years. They want to address in particular those teaching this topic to students and all those interested in understanding the technical basis.
Download or read book Plasma Science written by National Research Council and published by National Academies Press. This book was released on 2008-01-20 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of its current physics decadal survey, Physics 2010, the NRC was asked by the DOE, NSF, and NASA to carry out an assessment of and outlook for the broad field of plasma science and engineering over the next several years. The study was to focus on progress in plasma research, identify the most compelling new scientific opportunities, evaluate prospects for broader application of plasmas, and offer guidance to realize these opportunities. The study paid particular attention to these last two points. This "demand-side" perspective provided a clear look at what plasma research can do to help achieve national goals of fusion energy, economic competitiveness, and nuclear weapons stockpile stewardship. The report provides an examination of the broad themes that frame plasma research: low-temperature plasma science and engineering; plasma physics at high energy density; plasma science of magnetic fusion; space and astrophysical science; and basic plasma science. Within those themes, the report offers a bold vision for future developments in plasma science.
Download or read book Astrophysical Concepts written by Martin Harwit and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: My principal aim in writing this book was to present a wide range of astrophysical topics in sufficient depth to give the reader a general quantitative understanding of the subject. The book outlines cosmic events but does not portray them in detail-it provides aseries of astrophysical sketches. I think this approach befits the present uncertainties and changing views in astrophysics. The material is based on notes I prepared for a course aimed at seniors and beginning graduate students in physics and astronomy at Cornell. This course defined the level at which the book is written. For readers who are versed in physics but are unfamiliar with astronomical terminology, Appendix A is included. It gives a brief background of astronomical concepts and should be read before starting the main text. The first few chapters outline the scope of modern astrophysics and deal with elementary problems concerning the size and mass of cosmic objects. However, it soon becomes apparent that a broad foundation in physics is needed to proceed. This base is developed in Chapters 4 to 7 by using, as ex am pIes, specific astronomi cal situations. Chapters 8 to 10 enlarge on the topics first outlined in Chapter I and show how we can obtain quantitative insights into the structure and evolution of stars, the dynamics of co~mic gases, and the large-scale behavior of the universe.
