Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the 1991 calendar year activities of the fusion gamma ray diagnostics project in the Physics Department at the Colorado School of Mines. Considerable progress has been realized in the fusion gamma ray diagnostic project in the last year. Specifically we have achieved the two major goals of the project as outlined in last year's proposed work statement to the Office of Applied Plasma Physics in the DOE Division of Magnetic Fusion Energy. The two major goals were: (1) Solution of the severe interference problem encountered during the operation of the gamma ray spectrometer concurrent with high power levels of the neutral beam injectors (NBI) and the ICRH antenae. (2) Experimental determination of the absolute detection efficiency of the gamma ray spectrometer. This detection efficiency will allow the measured yields of the gamma rays to be converted to a total reaction rate. In addition to these two major accomplishments, we have continued, as permitted by the TFTR operating schedule, the observation of high energy gamma rays from the 3He(D, [gamma])5Li reaction during deuterium NBI heating of 3He plasmas.

Book excerpt: The development of D-T fusion-energy sources requires intimate and precise measurement of fusion-burn conditions in reactor-development experiments. Some of the limitations inherent in presently available diagnostics based on massive particle emissions can be overcome by measuring fusion-generated high-energy gamma rays. Although gamma-ray intensities are low, gamma rays offer diagnostic advantages of dispersion-free propagation and low intrinsic backgrounds. This paper describes two detector systems developed to study D-T fusion reactions by measuring the associated 16.7-MeV gamma-ray emissions. The first system is a Compton-recoil spectrometer and features good energy resolution of the 16.7-MeV photons. This system uses a sector-magnet spectrometer to isolate electrons forward-scattered by the high-energy gamma rays. The second system is a threshold Cerenkov detector and features a higher net sensitivity. A chamber filled with CO2 gas acts as a Cerenkov medium for electrons scattered by the 16.7-MeV photons. The gas pressure is adjusted so that electrons scattered by photons having energies less than 16.7 MeV do not have sufficient energy to generate Cerenkov light in the gas.

This book was released on 2012-12-06 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of proceedings collects the papers presented at the Workshop on Diagnostics for ITER, held at Villa Monastero, Varenna (Italy), from August 28 to September 1, 1995. The Workshop was organised by the International School of Plasma Physics "Piero Caldirola. " Established in 1971, the ISPP has organised over fifty advanced courses and workshops on topics mainly related to plasma physics. In particular, courses and workshops on plasma diagnostics (previously held in 1975, 1978, 1982, 1986, and 1991) can be considered milestones in the history of this institution. Looking back at the proceedings of the previous meetings in Varenna, one can appreciate the rapid progress in the field of plasma diagnostics over the past 20 years. The 1995 workshop was co-organised by the Istituto di Fisica del Plasma of the National Research Council (CNR). In contrast to previous Varenna meetings on diagnostics, which have covered diagnostics in present-day tokamaks and which have had a substantial tutorial component, the 1995 workshop concentrated specifically on the problems and challenges of ITER diagnostics. ITER (the International Thennonuclear Experimental Reactor, a joint venture of Europe, Japan, Russia, and the United States, presently under design) will need to measure a wide range of plasma parameters in order to reach and sustain high levels of fusion power. A list of the measurement requirements together with the parameter ranges, target measurement resolutions, and accuracies provides the starting point for selecting a list of candidate diagnostic systems.

This book was released on 2012-12-06 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of proceedings collects the papers presented at the workshop on "Diagnostics for Experimental Fusion Reactors" held at Villa Monastero, Varenna (Italy) September 4-12, 1997. This workshop was the seventh organized by the International School of Plasma Physics "Piero Caldirola" on the topic of plasma diagnostics and the second devoted to the diagnostic studies for the International Thermonuclear Experimental Reactor (ITER). The proceedings of the first workshop on ITER diagnostics were published by Plenum Press in 1996 with the title "Diagnostics for Experimental Thermonuclear Fusion Reactors". While many of the ideas and studies reported in the first workshop remain valid, there has been sub stantial progress in the design and specification of many diagnostics for ITER. This moti vated a second workshop on this topic and the publication of a new book of proceedings. ITER is a joint venture between Europe, Japan, Russia and USA in the field of con trolled thermonuclear fusion research. The present aim of ITER is to design an experimental fusion reactor that can demonstrate ignition and sustained burn in a magnetically confined plasma. To achieve this goal, a wide range of plasma parameters will have to be measured reliably. It is also anticipated that diagnostics will be used much more extensively as input to control systems on ITER than on present fusion devices and this will require increased relia bility and long-term stability.

Available in PDF, EPUB and Kindle. Book excerpt: Thermonuclear fusion could offer a feasible and sustainable solution to future energy production needs. In this book, internationally prominent experts present lectures on their experiences with fusion reactors, sharing comprehensive information on diagnostic methods and how to interpret the results obtained with different methods. The lecturers focus on diagnostic developments for a tokamak demonstration fusion reactor (DEMO) and for the International Thermonuclear Experimental Reactor (ITER), which will face unprecedented challenges: as it uses tritium to fuel the reaction, it also produces extremely high temperatures, high-energy neutron flux and intense gamma radiation. The lectures cover a diverse range of topics, including magnetic fusion confinement (tokamak, stellerators), Inertial Confinement Fusion lasers, and plasma physics, with a particular focus on measurement applications and associated physics in connection with ITER and DEMO. They describe current developments in theory and experiments, while also discussing the fundamentals of this fusion reactor technology field. As such, the lectures offer a valuable resource for all students and researchers who are new to the field.

Book excerpt: Diagnostics for the National Ignition Facility (NIF)/Inertial Confinement Fusion (ICF) program must include good characterization of the fusion source. Ideally, diagnostics would measure the spatially-resolved history of the fusion reaction rate and temperature. Existing diagnostics can satisfy this goal only partially. One class of new techniques that could play a major role in high-yield diagnostics is measurements based on fusion [gamma] rays. The Fusion Diagnostic Gamma Experiment (FUDGE) can be used to perform energy-resolved measurements of (D, T) fusion reaction rates This diagnostic is based on the 16 7-MeV [gamma] rays that are produced by (D, T) fusion. The [gamma] rays are free of spectral dispersion and can be detected with a high bandwidth Cherenkov detector. A simple magnetic monochromator selects signals from the 16 7-MeV [gamma] rays and reduces background signals from non-fusion [gamma] rays.

Book excerpt: As the yields of Inertial Confinement Fusion (ICF) experiments increase to NIF levels new diagnostic techniques for studying details of fusion burn behavior will become feasible. The new techniques will provide improved measurements of fusion burn temperature and history. Improved temperature measurements might be achieved with magnetic spectroscopy of fusion neutrons. High-bandwidth fusion reaction history will be measured with fusion-specific [gamma]-ray diagnostics. Additional energy-resolved [gamma]-ray might be able to study a selection of specific behaviors during fusion burn. Present ICF yields greater than 1013 neutrons are sufficient to demonstrate the basic methods that underlie the new techniques. As ICF yields increase, the diagnostics designs adjusted accordingly in order to provide clear and specific data on fusion burn performance.
