Book Description
Magnetic Fusion Energy: From Experiments to Power Plants is a timely exploration of the field, giving readers an understanding of the experiments that brought us to the threshold of the ITER era, as well as the physics and technology research needed to take us beyond ITER to commercial fusion power plants. With the start of ITER construction, the world's magnetic fusion energy (MFE) enterprise has begun a new era. The ITER scientific and technical (S&T) basis is the result of research on many fusion plasma physics experiments over a period of decades. Besides ITER, the scope of fusion research must be broadened to create the S&T basis for practical fusion power plants, systems that will continuously convert the energy released from a burning plasma to usable electricity, operating for years with only occasional interruptions for scheduled maintenance. - Provides researchers in academia and industry with an authoritative overview of the significant fusion energy experiments - Considers the pathway towards future development of magnetic fusion energy power plants - Contains experts contributions from editors and others who are well known in the field

Book Description
"Understanding the origin of rotation in Ion Cyclotron Resonance Frequency (ICRF) heated plasmas is important for predictions for burning plasmas sustained by alpha particles, being characterized by a large population of fast ions and no external momentum input. The angular velocity of the plasma column has been measured in JET H-mode plasmas with pure ICRF heating for both the standard low toroidal magnetic ripple configuration, of about ~ 0.08% and, for increased ripple values up to 1.5 % [1]. These new JET rotation data were compared with the Rice scaling [2] for the Alfven-Mach number and with the scaling for the velocity change from L-mode into H-mode."--Abstract.

Book Description
In this proceedings, physicists from all over the world discussed the state-of-the-art in the field of Electron Cyclotron Emission (ECE) and Electron Cyclotron Resonance Heating (ECRH) in great detail. Papers have been presented in the field of millimeter wave technology for ECE and ECRH, theory of propagation and absorption of EC waves in plasmas, EC current drive theory and experiments, nonlinear effects, ECRH sources, transmission line technology, experiments and plans. Comprehensive summaries on the main topics of the EC-10 workshop (theory, diagnostics, experiments, techniques) have been written by world renowned experts. The proceedings is indispensable for anyone who is working in the field of ECE and ECRH.

Book Description
Ion Cyclotron Resonance Heating (ICRH) powers of up to 17 MW have been coupled to JET limiter plasmas. The plasma stored energy has reached 7 MJ with 13 MW of RF in 5 MA discharges with Z/sub eff/ = 2. When I/sub p//B/sub [phi]/ = 1 MA/T the stored energy can be 50% greater than the Goldston L mode scaling. This is due to transient stabilisation of sawteeth (up to 3 s) and to a significant energy content in the minority particles accelerated by RF (up to 30% of the total stored energy). Central temperatures of T/sub e/ - 11 keV and T/sub i/ = 8 keV have been reached with RF alone. (He3)D fusion experiments have given a 60 kW fusion yield (fusion rate of 2 × 1016 s/sup /minus/1/ in the form of energetic fast particles (14.7 MeV(H), 3.6 MeV(He4)) in agreement with modelling. When transposing the same calculation to a (D)T scenario, Q is predicted to be between 0.l2 and 0.8 using plasma parameters already achieved. For the first time, a peaked density profile generated by pellet injection could be reheated and sustained by ICRF for 1.2 s. Electron heat transport in the central region is reduced by a factor 2 to 3. The fusion product n/sub io/[tau]/sub E/T/sub io/ reaches 2.2 × 102° m/sup /minus/3//center dot/s/center dot/kev in 3 MA discharges which is a factor of 2.3 times larger than with normal density profile. 18 refs., 13 figs., 3 tabs.
