Book excerpt: TFTR has begun its campaign to study deuterium-tritium fusion under reactor-like conditions. Variable amounts of deuterium and tritium neutral beam power have been used to maximize fusion power, study alpha heating, investigate alpha particle confinement, and search for alpha driven plasma instabilities. Additional areas of study include energy and particle transport and confinement, ICRF heating schemes for DT plasmas, tritium retention, and fusion in high[beta][sub p] plasmas. The majority of this work is done in the TFTR supershot confinement regime. To obtain supershots, extensive limiter conditioning using helium fueled ohmic discharges and lithium pellet injection into ohmic and neutral beam heated plasmas is performed, resulting in a low recycling limiter. The relationship between recycling and core plasma confinement has been studied by using helium, deuterium and high-Z gas puffs to simulate high recycling limiter conditions. These studies show that confinement in TFTR supershots is very sensitive to the influx of neutral particles at the plasma edge.

This book was released on 2019-02-15 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulence in plasma surface interaction holds crucial uncertainties for its impact on material erosion in the operation of fusion reactors. In this thesis, the design, development and operation of a Thomson scattering diagnostic and its novel implementation with fast visual imaging created a versatile tool to investigate intermittently occuring plasma oscillations. Specifically, ballistic transport events in the plasma edge, constituting turbulent transport, have been targeted in this thesis. With the help of a custom photon counting algorithm, the conditional averaging technique was applied on Thomson scattering for the first time to allow spatial and pseudo-time-resolved measurements. Since plasma turbulence and the emerging transport phenomena are comparable in most magnetized devices, the diagnostic development and the results from the linear plasma device PSI-2 are useful for an implementation of similar techniques in larger fusion experiments. Furthermore, the obtained results indicate a strong enhancement of erosion with turbulent transport and thus underline the importance of dedicated experiments investigating plasma turbulence in the framework of erosion in future fusion reactors.

This book was released on 1993 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic and plasma-material interaction processes play an important role in thermonuclear fusion plasmas and the knowledge of these processes has a significant impact on fusion energy research and development. The present volume provides a comprehensive survey of atomic and plasma-material interaction aspects of controlled thermonuclear fusion. The review articles included in this volume describe the role of atomic and plasma-material interaction processes in the currently most active fusion research areas and emphasize the need for accurate quantitative information on these processes for resolving many outstanding issues in fusion research and reactor design development such as plasma energy balance, particle transport and confinement, impurity control, thermal power and helium exhaust, plasma heating and fuelling, edge plasma physics, development of fusion reactor plasma facing components and plasma diagnostics and modelling.

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 2013-06-29 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for long-term energy sources, in particular for our highly technological society, has become increasingly apparent during the last decade. One of these sources, of tremendous poten tial importance, is controlled thermonuclear fusion. The goal of controlled thermonuclear fusion research is to produce a high-temperature, completely ionized plasma in which the nuclei of two hydrogen isotopes, deuterium and tritium, undergo enough fusion reactions so that the nuclear energy released by these fusion reactions can be transformed into heat and electricity with an overall gain in energy. This requires average kinetic energies for the nuclei of the order of 10 keV, corresponding to temperatures of about 100 million degrees. Moreover, the plasma must remain confined for a certain time interval, during which sufficient energy must be produced to heat the plasma, overcome the energy losses and supply heat to the power station. At present, two main approaches are being investigated to achieve these objectives: magnetic confinement and inertial con finement. In magnetic confinement research, a low-density plasma is heated by electric currents, assisted by additional heating methods such as radio-frequency heating or neutral beam injection, and the confinement is achieved by using various magnetic field configurations. Examples of these are the plasmas produced in stellarator and tokamak devices.
