The feasibility of CO/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 (<1/sup 0/) Thomson scattering. A computer simulation of the experiment indicates that a 100-MW pulsed laser combined with a bank of heterodyne receivers will be able to measure a scattered signal from the alpha particles with a postdetection signal-to-noise ratio of 75 for an assumed alpha density of 7.5 x 10/sup 11/ cm/sup -3/.
