Download or read book Thorium Energy for the World written by Jean-Pierre Revol and published by Springer. This book was released on 2016-04-05 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Thorium Energy Conference (ThEC13) gathered some of the world’s leading experts on thorium technologies to review the possibility of destroying nuclear waste in the short term, and replacing the uranium fuel cycle in nuclear systems with the thorium fuel cycle in the long term. The latter would provide abundant, reliable and safe energy with no CO2 production, no air pollution, and minimal waste production. The participants, representatives of 30 countries, included Carlo Rubbia, Nobel Prize Laureate in physics and inventor of the Energy Amplifier; Jack Steinberger, Nobel Prize Laureate in physics; Hans Blix, former Director General of the International Atomic Energy Agency (IAEA); Rolf Heuer, Director General of CERN; Pascal Couchepin, former President of the Swiss Confederation; and Claude Haegi, President of the FEDRE, to name just a few. The ThEC13 proceedings are a source of reference on the use of thorium for energy generation. They offer detailed technical reviews of the status of thorium energy technologies, from basic R&D to industrial developments. They also describe how thorium can be used in critical reactors and in subcritical accelerator-driven systems (ADS), answering the important questions: – Why is thorium so attractive and what is the role of innovation, in particular in the nuclear energy domain? – What are the national and international R&D programs on thorium technologies and how are they progressing? ThEC13 was organized jointly by the international Thorium Energy Committee (iThEC), an association based in Geneva, and the International Thorium Energy Organisation (IThEO). It was held in the Globe of Science and Innovation at the European Organization for Nuclear Research (CERN), Geneva, Switzerland, in October 2013.

Download or read book Particle Optics in High Intensity Accelerators written by J. G. Wang and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced high intensity accelerators have important applications in pulsed spallation neutron sources, synchrotron radiation light sources, radioactive ion beam facilities, etc. In contrast to traditional high energy physics accelerators, these high intensity accelerators require very high beam currents with relatively low particle energy. A common practice in the design of high intensity machines is to employ large aperture and short length magnets packed densely along beam lines in limited spaces. As a result, magnetic fringe fields become more profound, and the interference among adjacent magnets often causes problems for machine operation. This has become a new challenge for the design of high-intensity accelerators.This book describes how to solve the problems of magnetic fringe fields and interference, and how to correctly compute particle optics in advanced high intensity accelerators. The book has evolved from the authors research on the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The author has developed the theory and technique of 3D-field multipole expansion, assisted by advanced 3D-magnet modeling codes and Mathematica scripts. Advanced 3D-magnet modeling produces accurate, discrete magnetic field data on selected boundaries in magnets. With these simulation data, the 3D-field multipole expansion will produce quasi-analytic field distributions within the boundaries. Furthermore, with mathematical tools, particle optics in magnets can be accurately computed with the fringe fields and interference effects taken into account automatically.The author applied the new theory and technique to the SNS quadrupoles, dipoles, other magnets, and beam transport lines. His new approach also helped to discover and to solve the design problems of the SNS ring injection and extraction during the SNS ring commissioning. These practices are described in great detail in this book, and can be followed by the design of any other accelerator project. In addition, based on the comments and feedback from students and readers, the book also includes many important command input files and Mathematica scripts, which should be very useful and can be directly employed by readers to compute particle optics in their own machines.
Download or read book Accelerator Physics written by S Y Lee and published by World Scientific Publishing Company. This book was released on 2004-12-22 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of high energy accelerators began in 1911, when Rutherford discovered the atomic nuclei inside the atom. Since then, progress has been made in the following: (1) development of high voltage dc and rf accelerators, (2) achievement of high field magnets with excellent field quality, (3) discovery of transverse and longitudinal beam focusing principles, (4) invention of high power rf sources, (5) improvement of high vacuum technology, (6) attainment of high brightness (polarized/unpolarized) electron/ion sources, (7) advancement of beam dynamics and beam manipulation schemes, such as beam injection, accumulation, slow and fast extraction, beam damping and beam cooling, instability feedback, etc. The impacts of the accelerator development are evidenced by the many ground-breaking discoveries in particle and nuclear physics, atomic and molecular physics, condensed matter physics, biomedical physics, medicine, biology, and industrial processing. This book is intended to be used as a graduate or senior undergraduate textbook in accelerator physics and science. It can be used as preparatory course material for graduate accelerator physics students doing thesis research. The text covers historical accelerator development, transverse betatron motion, synchrotron motion, an introduction to linear accelerators, and synchrotron radiation phenomena in low emittance electron storage rings, introduction to special topics such as the free electron laser and the beam-beam interaction. Attention is paid to derivation of the action-angle variables of the phase space, because the transformation is important for understanding advanced topics such as the collective instability and nonlinear beam dynamics. Each section is followed by exercises, which are designed to reinforce the concept discussed and to solve a realistic accelerator design problem.

This book was released on 2006-07-24 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume in a series of lecture notes based on the highly s- cessful Euro Summer School on Exotic Beams that has been running yearly since 1993 (apart from 1999) and is planned to continue to do so. It is the aim of the School and these lecture notes to provide an introduction to - dioactive ion beam (RIB) physics at the level of graduate students and young postdocs starting out in the ?eld. Each volume will contain lectures covering a range of topics from nuclear theory to experiment to applications. Our understanding of atomic nuclei has undergone a major re-orientation over the past two decades and seen the emergence of an exciting ?eld of research: the study of exotic nuclei. The availability of energetic beams of short-lived nuclei, referred to as radioactive ion beams (RIBs), has opened the way to the study of the structure and dynamics of thousands of nuclear species never before observed in the laboratory. In its 2004 report “Persp- tives for Nuclear Physics Research in Europe in the Coming Decade and - yond”, the Nuclear Physics European Collaboration Committee (NuPECC) statesthatthe?eldofRIBphysicsisoneofthemostimportantdirectionsfor the future science programme in Europe. In 2005 it published its “Roadmap for Construction of Nuclear Physics Research Infrastructures in Europe”.
Download or read book Neutron Detectors for Scattering Applications written by Yacouba Diawara and published by Springer Nature. This book was released on 2023-08-04 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most common neutron detectors used in neutron scattering facilities and all of those in use at Oak Ridge National Lab. It starts describing the facilities, instruments and the critical detector parameters needed by various instruments. Then the key components of the 3He-based linear position-sensitive detectors as well as on their electronics, which require particular attention to signal processing and noise reduction, are introduced. One chapter is dedicated to the 3He alternatives where scintillators play a critical role. It also covers emerging neutron detection technologies including semiconductors, vacuum-based devices and their associated readouts, which will be required in the future for high rate and high-resolution neutron detectors. The authors explain the logic behind the choice of materials as well as the various constraints that neutron detectors must respect to be useful. Some of these constraints, such as efficiency and gamma-ray sensitivity are common to all neutron counters while others, like timing resolution, dynamic range, and peak counting rate, depend on the applications. The book guides experts, the nuclear science community, and young scholars through the physical processes and the required electronics in a way that is accessible for those not professionally involved in designing detector’s components and electronic circuits.
