Book excerpt: We investigate the possibility of seeding a fusion plasma with nuclei which can undergo nuclear reactions with energetic alpha particles to produce product nuclei which are radioactive. If a fraction of these product nuclei can be collected and measured, one can obtain information about the presence of fast alpha particles. It appears that a feasible diagnostic could be based upon the 1°B(.cap alpha., n)13N reaction.

Available in PDF, EPUB and Kindle. Book excerpt: In this work the photographic emulsion technique has been applied to the study of the long range particles given off during neutron irradiation of uranium. Alvarez first observed these particles with an ion chamber and linear amplifier. Segre, et al (LA-87) studied these particles with an ion chamber which gave coincidences between these particles and fission. They found them to be coincident with fission within the time constant of their circuit (approx 5u sec). They were also able to identify these particles as alpha particles from the density of ionization near the end of the tracks. Hughes has observed a number of these alpha particles in the cloud chamber, but his setup did not permit him to observe the associated fission track. The cloud chamber or photographic emulsion technique permits information to be obtained about the alpha particles and their association with the fission process that cannot be got by the ion chamber method. The photographic emulsion technique has been used in this case because it lends itself very well to a study of rare events of this type.

Download or read book Method for Determining Fast alpha particle Confinement in Tokamak Plasmas Using Resonant Nuclear Reactors written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The resonant nuclear reactions D(.cap alpha., .gamma.)6Li, 6Li(.cap alpha., .gamma.)1°B, and 7Li(.cap alpha., .gamma.)11B are examined as diagnostics of fast-alpha-particle confinement in tokamak plasmas. Gamma rays from these resonant reactions with energies from 2.1 MeV to 9.2 MeV may be used to infer the alpha-particle population between energies of 0.4 MeV and 2.6 MeV. The ratio of these alpha-burnup reactions to the reactions T(D, .gamma.)5He and 3He(D, .gamma.)5Li provides a technique for the measurement of alpha confinement.

Book excerpt: The study of burning plasmas is the next frontier in fusion energy research, and will be a major objective of the U.S. fusion program through U.S. collaboration with our international partners on the ITER Project. For DT magnetic fusion to be useful for energy production, it is essential that the energetic alpha particles produced by the fusion reactions be confined long enough to deposit a significant fraction of their initial ~3.5 MeV energy in the plasma before they are lost. Development of diagnostics to study the behavior of energetic confined alpha particles is a very important if not essential part of burning plasma research. Despite the clear need for these measurements, development of diagnostics to study confined the fast confined alphas to date has proven extremely difficult, and the available techniques remain for the most part unproven and with significant uncertainties. Research under this grant had the goal of developing diagnostics of fast confined alphas, primarily based on measurements of the neutron and ion tails resulting from alpha particle knock-on collisions with the plasma deuterium and tritium fuel ions. One of the strengths of this approach is the ability to measure the alphas in the hot plasma core where the interesting ignition physics will occur.

Download or read book Alpha emitting Particles in Lungs written by National Council on Radiation Protection and Measurements and published by Ncrp. This book was released on 1975 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In recognition of the fact that the potential for release of particulate plutonium and transplutonium alpha-emitting elements fromm nuclear power generation facilities poses questions concerning spatial distribution of dose and the resultant biological effects, the NCRP initiated a new NCRP activity concerned with alpha-emitting particles in lungs. It was not intended that a complete review of the subject would be prepared. On the other hand, the study was not to be directed exclusively to recently promulgated controversial proposals relating to standards for alpha-emitting particles in the lung. Rather, the new effort was intended to be a limited-scope study aimed at the development of a statement on the question of whether the current practice of averaging over the lungs the absorbed dose from particulate alpha-emitting radionuclides is a defensible procedure in the practice of radiation protection, and whether exposure limits derived on this basis are more, or less, conservative than those that might result from a precise consideration of the spatial distribution of the dose." --From Preface, page iii.
