Book excerpt: Fusion-product alpha particles will dominate the behavior of the next generation of ignited D-T fusion reactors. Advanced diagnostics will be required to characterize the energy deposition of these fast alpha particles in the magnetically confined plasma. For small-angle coherent Thomson scattering of a CO/sub 2/ laser beam from such a plasma, a resonance in the scattered power occurs near 90/sup 0/ with respect to the magnetic field direction. This spatial concentration permits a simplified detection of the scattered laser power from the plasma using a heterodyne system. The signal produced by the presence of fusion-product alpha particles in an ignited plasma is calculated to be well above the noise level, which results from statistical variations of the background signal produced by scattering from free electrons. 7 refs.

Book excerpt: The feasibility of O/sub 2/ laser Thomson scattering from a multicomponent burning plasma has been evaluated for the measurement of the velocity distribution of D-T produced alpha particles. The density and velocity distribution of the alpha particles from their initial energy of 3.5 MeV down to near-thermal energies may be measured by small angle (

Book excerpt: The optimization of a CO[sub 2] laser Thomson scattering system for measurement of the velocity distribution of fusion product alpha particles is studied. It is found that for the International Thermonuclear Experimental Reactor (ITER) plasma, the optimal system conditions are a 20-MW source laser and a receiver bandwidth of 15 GHz.

Available in PDF, EPUB and Kindle. Book excerpt: Methods are proposed for measuring the alpha-particle distribution in magnetically confined fusion plasmas using neutral-atom doping beams, ultraviolet spectroscopy, and neutral particle detectors. In the first method single charge exchange reactions, A° + He/sup + +/ -> A (He)*, are used to populate the n=2 and n=3 levels of He+. The ultraviolet photons from the decaying excited states are Doppler shifted by 5 to 10 Angstroms from those produced by the thermalized alpha-particle ash. In the second method double charge exchange reactions, A° + He/sup + +/ -> A/sup + +/ + He°, enable fast neutralized alpha-particles to escape from the plasma and be detected by neutral particle analysers. Detector configurations are analyzed, count rates are estimated and their detectability is discussed. A preliminary analysis of the feasibility of the required neutral beams is presented, and exploratory experiments on existing devices are suggested.
