The feasibility of scattering CO/sub 2/ laser radiation from a multi-component 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 due to the alpha particles for an assumed alpha density of 5 x 10/sup 11/ cm/sup -3/.
